I have an DL06 that port2 is connected via 232 to a SureServo Drive, I am using the modbus protocal standard RTU. On port1 I am hooked to an EZTouch Panel.
What happens is it works a little here and there, then locks up, and the coms drop out of the HMI. If controlling the SS drive through the Modbus it is a **** shoot if it works or not.
I have checked all the wires, Device numbers, protocol types for matching. The PLC just doesnt seam to be able to recieve info from the Drive. (The parameters are all mapped per the manual as well).
I had heard rumor that there is an issue between Port1 and Port2 when one of the ports is running Modbus and the other is something different. Another guy told me I should run 422 to the Drive instead of 232, (so doing that now). The 06 is device 1, and the drive is device 2.
