Would you happen to know if there is memory that is specifically reserved for the servo pack and the Omron? Since I have no descriptions of any kind, I am trying to isolate where data may be getting transferred from the PLC to the Servo pack.
The Motion card (CS1W-MC421) communications via hard wire with the Yaskawa servo pack. The memory areas used between the MC card and the PLC can be found in the MC card manual:
W359-E1-04, Section 5-1, page 226 to 234. and more Section 5-3, page 248 to 260.
The above paragraph assumes we are talking about a CS1W-MC421 card in the CS1G PLC
If your system has a C200H-MC421 card in the CS1G PLC, you must convert memory areas. (C200H-MC421 is an extremely old card)
See Manual W339-E1-15A Section 9-3, page 412.
In both types of motion cards, the memory areas will also be dependent on the "unit #" (also called "Mach #"). The unit number assigned by the system designer (rotary switch on front of MC card) to the Motion card (special I/O card) If the unit # is "0" than the manual spells out the memory areas clearly. Info on unit # in Manual W359-E1-04, Section 2-1, Page 103.
Hope this helps
