Please look  here and scroll down for the latest list as an xlsx:


Are the comms to the drivers being done with 485 or 232?  The settings in the PLC to communicate with the drives is likely upsetting things, but it should still be possible using the default port and plugging in to no. 1.  Another possibility (that can only be done after you've got into the 120) is that your 120 can do UniCAN which might be a simple way to allow this if you got a 130 with no I/O and just a Canbus adapter, and linked the 120 and 130 together.  You could then get into the 120 via the linked 130.  Or alternatively completely change up to a 130 that can be fitted with an extra com module and also an ethernet one, which would do the same job but with the added benefit of getting in all the time via ethernet, all in one unit.  Changing the code to a 130 is not that hard.  In fact there is a facility in Visilogic to help do this.

cheers, Aus
