  1. Hi everyone, I'm facing problems implementing the Easy modbus-rtu master solution kindly provided by PMCR. i'm working with a CJ2M, and i have a SCU41-v1 connected to 5 AC10 series Parker drives, using modbus at Port 1 (Protocol Macro as indicated in the manual- 2 wire). Everything works ok after powering up the system. Unfortunately, after a few minutes, one of the parker drives freezes communication. An hour later....another. And so on. If I reboot the drive, powering it off and on, it starts communicating again. Any ideas about what might be causing this? Thanx.
  2. Hi everyone, I want to connect Allen Bradley 1756-L63 cpu (slave) via RS-232 port to ABB CI-853 (I don't have Prosoft MVI-56-MCM that can easily solve my situation). The only way that I found is application ModbusSlave.ACD (cig-ap129_-en-p.pdf). Do I need AIC+ converter (1761-NET-AIC) or can I connect with cable (DB9-to-RJ45)? Is there another way to make this connection? Regards, Luka
  3. Im trying to control a baldor VFD trough modbus RTU with cp1h/cp1wcif12 using the solution posted here which for me works really fine but the problem comes when I turn on the motor (500hp 440v), the cable gets induced and adds noise to the communication causing errors when reading. I already try to use shielded cable and it gets better but still causing errors. In the solution posted in the link above shows how to connect the cp1w-cif12 by connecting only SDA- and SDB+. So my question is, should I connect FG to the VFD rs-485 ground as well to reduce that noise? Any suggestions are welcome
