  1. Hello all, We would ask you for help or advice, we have some problems with communication between this two PLC-s V1210 ( moduleV200-18-E46B) and remote I/O EXF-RC15 via CAN bus. We control with 5 servo motors (Yaskawa), two of them is controlled by V1210 and other 3 by EXF-RC15. Everything keeps smooth when we control only 2 motors which are attached to V1210. Problems starts when we finish programming some of other three motors controlled by EXF-RC15 - (when we need communication between this two PLC-s’9. For example when we push on run bit for one motor (Button on V1210 display), its pushes on all other motors run bit etc. We send data about run bits from EXF-RC15 to V1210, but cant send same in other way and for that reason RC15 does not send to V1210 info when run bit is off ? At the and we solved problem with auxiliary bits through ladder logic but we really want to know what is problem. In attachment u can find both programs, i hope that you will look at it, and give us some advice... We would really appreciate any kind of help.... RC15.vlp V1210.vlp
  2. Hello, I am working on a project with the V130 PLC, I have 6 separate actuators connected to my slave configured PLC which communicate over CANbus J1939. I have trouble with controlling the actuators in a consecutive way, some of the times the actuators respond to the command that I send them and sometimes not. I think it might be related to the configuration of the J1939 PGNs on Visilogic. If someone can help that will be great, I am attaching my configuration of transmit and receive PGNs. Thank you, Yom
  3. Hello, I'm working on my first CANopen project where a frequency drive is controlled using the Vision 1210. However i can't seem to figure out how i can start this drive. According to the CAN Bus Operation PDF i should be able to control the drive using PDO 1, as it's default mapping is the control command register. To start the drive bit 0 from register 2000 must be set. but how can i set bit 0 using canbus? CAN Bus Operation.pdf FENNER_QDNEO_S2-S3_CANopen 2.00.eds
  4. Hi. Hope someone can assist. Installed 8 v570 units at client. First tried ethernet, then canbus and then modbus. No luck. Sometimes plc loose comms with other plc's and sometimes some plc's loose comms with omron cx supervisor scada. Any assistance will be appreciated. Thanks. Rodger
  5. Hello! I need to communicate with an external device using CANbus, Layer 2standard. I have a question regarding the stored values. The external device sends Unitronics PLC 8 bytes of data. Let's assume the data frame first two bytes are byte 0, (most significant bit) : AA BB and byte1 CC DD. I will store the values in Mi's, starting with Mi0. How is the data saved? Does the MSB stay as MSB, so that the MI0 value would be AA BB (43707 in DEC) and MI1 would be CCDD( 52455 in DEC). Or the outcome would be Mi0= CCDD, Mi1=AABB? Thanks in advance!
  6. Hi All, I have 3 Jazz PLC's communicating over Modbus with JZ-RS4, 1 master (R31) and 2 slaves(R10). Is there a way to check for errors in comms, Rx & TX. If comms fail, to reset all outputs on both slaves. (similar to CanBus "check alive function") thanks Matt
  7. Dear all; I have a problem with the canbus comunication. I need to connect a PLCV130 with a OPLC1210 and 2 EX-RC1. I started with the communitacion between a OPLC 1210 (ID#1) and one EX-RC1 (ID#2), I am using the help´s program (V570_CAN Master for EX-RC1 for PLC, and the other for the EX-RC1). With the EX-RC1 I have an IO-DI16. But it has been impossible to me to make this connection. The PLC and one EX-RC1 dont see each other in the canbus network Any advice for me thanks. I appreciate your help
  8. Does the EX-RC1 support the same functions, such as drum sequencer, as the vision series?
  9. We use several workstations that may, or may not be, running at any given time. How well does the CANbus protocols handle a node being offline?
  10. Hi All, Good day. I am very new to Unitronics. Now I setup V1210 and connected to EX-RC1 via canbus and added IO-DI8-RO4 to EX-RC1 I went throungt Unitronics tutorial to configure the above hardware with no luck. In order to understand, I need sample program to work with above setup. On loading the sample progrm, I should be able to test by simulating the IOs on the IO-DI8-RO4 Kindly assist. Also I would like to know if I can do all the configuration using visilogic alone or I will have to use unilogic? It is confusing to me, Please help thanks and best regards K.Parimalam
