	Is it possible to configure an MPiec Series Controller as a Modbus/TCP slave or Ethernet/IP adapter? Posted Date: 12/05/2008 Answer: Yes, an MPiec Series Controller can be configured as a slave for both protocols simultaneously if required. Simply set the appropriate checkboxes in Ethernet/IP or Modbus/TCP sections of the Hardware Configuration using MotionWorksIEC software. Based on the network topology, verify the controller's default gateway is set appropriately. Global variable groups will be automatically created, which will list the associated IEC addresses to use. The programmer must add Modbus/TCP or Ethernet/IP variables to the groups in the Global variable list. Please check the Hardware Configuration manual, section 1.9.2 and 1.9.4 for more memory map details.

	Is it possible to configure a LEGEND-MC to communicate with a 3rd party PLC over Ethernet TCP/IP with Modbus protocol? Posted Date: 10/26/2005 Answer: Yes. Attached are examples of an MP920 system communicating with a LEGEND-MC over ethernet, the same philosopy can be used with 3rd Party PLCs using Modbus over TCP/IP. The following is a description of the setup: HARDWARE SETUP: - The MP920 Rack system uses a 218 ethernet I/F module with an ethernet 10Base-T RJ45 Transceiver module (Model E-TBT-MC02 made by Transition networks). Essentially, the MP920 represents any third party PLC that can communicate Modbus over TCP/IP Ethernet. (Alternate Transceiver module available from Focus Networks (www.signamax.com) part number 065-2160, description 10BaseT RJ45 Ethernet Transceiver module for $33.00 - Call CSC in Chicago @ 800-446-2377.) - The 218If module also needs a +12VDC power supply, a wall mount supply is sufficient for testing. - The LEGEND-MC, MP920 System, and PC are all linked together via a DS108 Dual Speed 8-port hub made by Netgear. Category 5e ethernet patch cables by Belkin (Model: R7J304 4 pair 24 awg) were used for interconnection. - The system is physically connected and verified for connection at the HUB: Hub is connected to the building network via port#8 with the uplink engaged and receive LED blinking. PC connected @ port#1 shows 100M LED ON. LEGEND-MC connected at port#2 shows 10M LED ON. MP920 218 connected at port#3 shows 10M LED ON. For additional information on obtaining 3rd party hardware for this setup see this FAQ CONFIGURATION: - In this set-up, it is important to point out that the LEGEND-MC will be the master on the network, controlling data transfer to and from the MP920 or PLC over ethernet. The limitation in this configuration is 8 handles in each master LEGEND-MC and 8 handles in each MP920 (and a master typically requires two handles for a connection to a slave). - The PC is set up as IP address 192.168.1.21 - To set up the MP920, it will be necessary to first expand the MP920 program, "Cpu1.zip", into a temporary directory from Windows Explorer. Next, from MW, using the standard CP Ladder editor, create a new MP920 CPU. Lastly, from Windows Explorer copy the folders under the CPU1 temporary directory from above and paste them into the C:\YEToos\Cp717Usr\.... (make sure to select the proper order and controller folders). - The MP920 program attached is configured for station IP address 192.168.1.200 via software port (which is the standard port for Modbus), and utilizes a modbus function block in the low speed ladder L01. At this point, it should be possible to log into the MP920 controller via MW and find the L01 drawing with the function block as described (see attachment below). Note that this example shows its usage in the CP ladder editor. When online, do a full transfer from HD to CPU. Then, cycle power on the MP920 system. - To verify a connection, it is possible to use the "PING" utility from the MSDOS prompt (see below for example of a successful response to a PING command on the MP920 IP address). Note: if the MP920 is not responding, it may be necessary to cycle power on the system. - The SMC3010 is set up as IP address 192.168.1.29 and assigns the MP920 connection on handle E. This is defined in the attached setup program, "Tcpmtst1.smc". From YTERM, connect to the LEGEND-MC, download the program, and execute it with the XQ command. Pay special attention to the messages on the screen. TC1 will also indicate any problems. - To verify that the handle E connection has been made, an ethernet utility "Vcomm" is available from the YTerm installation CD. Launching this program will connect to the LEGEND-MC (use IP address 192.168.1.29 as indicated above). Verify the data is similar to that shown in the "Vcomm alpha" example window attached below. RUNNING THE PROGRAM: - The attached program, "Tcpmtst2.smc", is a test progam to write registers (6 registers starting from MW00000) over TCP Modbus from the LEGEND-MC to the MP920, and then read them back out again. After downloading and executing this program, verification of variables VAR10, 11, 12, 13, 14 should read the same as those set in VAR0,1,2,3,4. To monitor the data from the MP920, simply verify via the "Register List" in MW. Note that the first 4 are 16-bit words and should be monitored as MW registers and the last one is 32-bit long and should be monitored as an ML register.

	Is it possible to calculate the scan time of the program running in the SMC? Posted Date: 06/25/2013 Answer: Yes. There is a keyword in the system called "TIME" which counts the number of milliseconds (servo cycles) since the power was turned on or the system was reset. Examine the following program: #TEST START=0 #LOOP SB4 X=X5 Y=4/2 Z=XY CB4 SCAN=TIME-START START=TIME JP #LOOP The value of SCAN will be updated to reflect the number of milliseconds since teh user variable START was last assigned. TIME is in servo cycles, which by default is milliseconds. If the TM command is changed, TIME will change accordingly. If the TM parameter is reduced by half, the SCAN value will be twice as much. Below is an example that will take into account any TM value so SCAN will always be in milliseconds. #TEST START=0 #LOOP SB4 X=X5 Y=4/2 Z=XY CB4 SCAN=(TIME-START) * (_TM/1024) // MG SCAN START=TIME JP #LOOP If you print the value of SCAN from a small program loop, the process of displaying the message (MG SCAN) may take a considerable amount of the actual program loop, resulting in erroneously larger program scan times. Processing characters for the serial port is very show compared to program execution speed. It is recommended to use the LV command or type MG SCAN when the scan value is needed. If there are trip point commands in the program loop, they of course may add time to the loop based on the trip point delay period.

	Is it possible to automatically start an HMI recipe download from an SMC-3010 controller? Posted Date: 06/26/2013 Answer: Yes, by using the interlock mailbox. In many cases upon a machine power on sequence, it is desireable to automatically load up a series of custom startup parameters (or recipe of values) from an HMI interface into the controller for use in operation. In this case, a LegendMC (SMC-3010). Below we describe what is necessary to configure an EXOR HMI to transfer a recipe of values to the controller, at the controller command, by utilizing an "interlock mailbox" feature. Step 1: Definition of the mailbox In the EXOR Designer software (reference Designer User Manual), enable the mailbox to "read in cycles" from Project/Interlock Mailbox.. menu dropdown. Click on the "Reference.." button to access the base controller variable where the mailbox data will be exchanged. Select "0" for 16-bit word format (WORD [bin]) see screen shots below). In this case, we will define the controller variable "V050" as the start of the mailbox. According to EXOR designer manual, each word in the mailbox is defined to be 16 bits wide, since SMC3010 defines integers as 32 bit words, care must be taken when setting up the mailbox structure (see table 8-1 of Designer manual). In this case, the first word of the mailbox (cmd/status word) will be the first 16 bits of "V050", the second word of the mailbox (function/response code) will be the second most significant 16 bits of "V050", the third word of the mailbox (parameter 0) will be the first 16 bits of "V051", and so on. Twenty 16-bit words should be reserved for the mailbox, so the controller should pre-define and set asside 10 variables, such as "V050" thru "V059" or UniOP[0] thru UniOP[9]. NOTE: it is very important to pre-define these words in the controller or this will not work, see the SMC code example attached. V050 low 16 bits = Cmd/Status Word V050 high 16 bits = Function/Response Code Word V051 low 16 bits = Parameter 0 V051 high 16 bits = Parameter 1 ...etc... Step 2: Commanding Recipe Download from Controller Refer to 8-6 of Designer Manual. In the case of recipe download, the Cmd/Status word and Function/Response code will share the same controller variable (in our example "V050") because it is 32 bits wide. Step 2A: First the mailbox parameters should be set. Parameter 0 should be set to the page number that the recipe is located (for example page 7) and Parameter 1 will be set to the recipe set number (for example recipe set 4). EXAMPLE: In V051, enter 262151 in decimal or 40007 in hex (4 shifted 16 bits to the left, plus 7. In binary: 100 0000 0000 0000 0111) Step 2B: Next, the initiate the command. The Function Code should be set to "2" to "Start Recipe Download" and the CMD word should be set to "1" to indicate that there is a pending request. EXAMPLE: In V050, enter 131073 in decimal or 20001 in hex (2 shifted 16 bits to the left, plus 1. In binary: 10 0000 0000 0000 0001) Step 3: Confirm Recipe Download Completion After successful execution, the mailbox will return a "4" in the Cmd/Status word to indicate that the command has been completed, and a "0" in the Function/Response code to indicate that the transfer has been completed successfully. If an error occured, it will indicate in the Function/Response code area. A table of error codes can be viewed in Designer manual table 8-5. EXAMPLE: V050 will display 4 in decimal or 00004 in hex (4 shifted 16 bits to the left, plus 0. In binary: 100 0000 0000 0000 0000) Note: To set a hex value in the SMC-3010, you would use the "$" symbol. Example in step 2A: "V050=$40007" Note: In order to use the mailbox, the HMI must interpret the controller word as two 16 bit words in stead of one 32 bit integer word. To accomodate for this, a new driver has been created and has been attached below.

	Is it possible to add external regen resistors to the SGDG LEGEND amplifiers? Posted Date: 08/13/2002 Answer: Yes. External regen resistor can be added to the SGDG-10GT and SGDG-15GT by connecting it across terminals B1 & B2. Switch SW1-5 should be turned OFF when external regen resistor is added. The LEGEND SGDG-01GT & SGDG-04GT needs special attention when external regen resistor is required in the appication. External regen unit JUSP-RG08D must be used with the SGDG-01GT. The JUSP-RG08D is a self-contain unit consisting of DC bus sensing and alarm circuitry, switching IGBT, and a 50 ohm regen resistor. The JUSP-RG08D can also be used with the SGDG-04GT, or the user can order the SGDG-04GTY22P for regen applications only. The SGDG-04GTY22P must have two (2) RH500N25_ohmK resistors wired in series connected to it at all times. See attached document, eng02.027MCD, for more details.

	Is it possible to achieve more consistent I/O updates for high speed applications with the Mechatrolink Phoenix Bus Coupler and the MP2000 series products? Posted Date: 11/30/2010 Answer: There may be a delay in the in IO response when using the Phoenix bus coupler over the Mechatrolink. This could be caused by a large amount of IO being used and the time it takes for the Mechatrolink to update the IO status. As a result we recommend a phased approach to improve the IO responsiveness with the following steps: 1. I/O connected to the main body of the coupler will be faster than the additional slice I/O because of the additional time required by the backplane for processing of the remote I/O. Use main body I/O where possible for the most critical I/O. 2. Update the module's update rate to sync with the High speed scan program being used. If using an MP2000iec controller, be sure the I/O driver is set to update at an appropriate interval (synchronize with a task that corresponds to the desired I/O refresh rate.) 3. Move the critical I/O to an LIO card on the MP2000 series controller. 4. Move the critical output to the COIN connection on the LIO or CNTR-01 card. This is also referred to as the High Speed Output function on MP2000iec controllers. This is a hardware level function that can operate the output within 13 uSec of the encoder on the LIO card meeting an exact position value.

	Is it possible for outputs of an NS600 indexer to activate inputs of another NS600 indexer unit? Posted Date: 10/17/2002 Answer: Yes. In a multi axis system, this method of I/O manipulation is very useful. For instance in a 2 axis system, suppose the first axis has to make a move and get to a particular position before the second axis starts its motion. Once the first axis is in position, set an output to directly signal the secondary axis to start motion. When the second axis reaches its target position, it could set an output to tell the first axis the move is complete. The same concept can be applied for a series of index moves and stops. The Zone outputs are also very useful if mechanical interference between axes exists in certain positions. Set the Zone output after the first axis is out of the interference zone. Another axis could use this as an input to begin motion. The same concept can be applied to multiple mechanisms working in conjunction with each other.

	Is it possible for an SMC controller to do a PLS function? Posted Date: 07/13/2004 Answer: Yes, by using the MF or MR commands. After the trip-point clears, use the SB and CB commands to clear or set an output bit. This works very well when there are over six outputs that need to be fired in a very accurate amount of time. If there are 4 or less outputs, you can create a loop structure that uses the OB command like this OB [output],[logical condition] which will set and clear the outputs based on the logical condition being true or false. The SMC does not have built in PLS commands, but it is possible by programming with the above commands. It is also possible to use this PLS scheme on an external encoder and get the information over Ethernet to other controllers. The auxiliary encoder info goes over Ethernet, updated at the slave update cycle, which has a four mSec minimum. The limitation on the auxiliary encoder is that the MF and MR commands only work with main encoder axes, so you have to make a mini program loop that checks the position of the auxiliary encoder. The fastest way to a PLS on an auxiliary encoder is to fan it out to all controllers.

	Is it possible for an MP controller to ID the motor and amplifier connected via an SVB module? Posted Date: 08/19/2004 Answer: Yes, reading information via the M-Link network is possible. The motor type, power level, and encoder type data are contained in servo parameter number PnF00. Please refer to AHAR-5K8HL4 FAQ on how to read SGDH parameters. Reading this parameter requires two execution steps: 1. Set OWxx35 register to 1F00 (HEX). The most significant nibble indicates the 1-word of read data, and the first three nibbles specify the SGDH parameter number. 2. Change Motion Command Code register, OWxx20, to 17. This will cause the contents of PnF00 to be copied to holding register IWxx28. After the value is moved to the lower 16 bits of ILxx28 (IWxx28), the data can be interrupted as follows: Bits 0 ~7: Motor Type: 00: SGMAH 01: SGMPH 02: SGMSH 03: SGMGH_A 04: SGMGH_B Bits 8 ~11: Input Voltage: 00: 100VAC 01: 200VAC 02: 400VAC Bits 12 ~15: Encoder Type: 00: Incremental 01: Absolute Product Group/Line: Controllers, MP920 Machine Controller Topic/Sub Topic: Ask a Technical Question, Network Communications, Operation, Start Up - Installation Document Number: AHAR-5K8HS2 Published Date: 08/19/2004 Share \| Rate Rate this article :	08/19/2004
