What causes an 00h or 86h error in Vijeo Designer when communicating to a M221 PLC?
Product Line:
Magelis HMI Vijeo Designer, M221, Machine Expert Basic
Resolution:
The error message is due to the Magelis reading the discrete/analog inputs as %I or %IW from the PLC. You need to move the %I and %IW to %M and %MW in order to read the data from Vijeo Designer.
