  1. Hello, I have an application running at one of my customers, which there is a V1040 PLC communicating via Canbus with 7 EX-RC1 nodes of which two modules have been installed recently. Each EX-RC1 has a couple of expansion modules connected to it and exchange digital and/or analog data with the PLC. I have followed all the instructions on how to install and configure all the devices, and my application was working fine with 5 EX-RC1 nodes. The problem is, when I installed the others two nodes, my application started behaving strangely: The data (only MI's) coming f
  2. Hi, me again, having problems with Unitronics hardware. This time with module EX-RC1. After 3 months of operation the EX-RC1 module stopped working. CANbus network ceased to work so I had a look at RC1. Only the power LED was lit but I couldn't connect to the module via serial (I tried all bound rates) or canbus. I decided to unplug the module and test it in the "lab". So I connected it to 24 VDC and to serial connection via provided RS232 adapter. Only the power LED is lit and the module is not responding to any "request" via "Communication - PC setting" window in VisiLogic (late
  3. Hey all, I am new to Visilogic and I am trying to follow through tutorials. I am currently trying to interface a single EX-RC1 via CANBus to a V570. On the EX-RC1 I have a IO-DI16 and IO-RO16. I have tried to download the sample Visilogic programs to the PLC, however, I am not entirely sure if I am doing it correctly. I have flashed the V570_CAN Master for EX-RC1.vlp on the V570 successfully, however, the screen shows "COMM ERROR UNIT #2". When I tried to download the EX-RC1.vlp to the PLC it says "The PLC model selected in this project's Hardware Configuration conflicts with the mo
  4. Anyone ever have a problem trying to program an EX-RC1 in bridge mode over Ethernet? I have a v700 that is connected to three EX-RC1s. When I attempt to load new code to any of them using bridge mode, I'm getting a "retry binary transmit" message from Visilogic followed by an error 240. The download process then halts. Any insight would be appreciated. Regards, Mark
  5. Hey guys, I have a UniStream 7" PLC connected with EX-RC1 expansion module via CANBUS. The CANBUS is connected according to the info in the datasheet with 120 ohm resistors and everything. The complete configuration that the PLC communicates with from left to right is as follows: EX-RC1, 3 x IO_D16A3_RO16, 2 x IO_ATC8/AI8, IO_D16_A3_RO16. The PLC and the EX-RC1 is grounded and connected as it should. EX-RC1 is programmed (initialized UniCAN) and the LEDS are all working propperly (PWR ON, I/O COMM ON, BUS COMM ON). Accordingly I am able to read/write all the inputs/outputs. So,
  6. Hi everyone I'm fairly new at unitronics and I'm doing a project that calls for the use of two EX-RC1 connected by modbus. I've been going through the webinars ( and ) and I'm still in the dark as to how I set upthe EX-RC's for my I/O expansions. In my first RC I have the following I/O's : #0: D16A3-RO16 #1:AO6X 2#: AO6X #3: AO6X #4:AI8 #5AI8 In the second RC I have four IO-PT400 modules I've tried following the second youtube clip, using the EX-RC1 example file where I've added my I/O's, but I get an error when I try to export the Hardware config: 'Export failed
