When you use a BMECXM module on the Modicon M580, observe these limits:

1. Each BMECXM module can manage a maximum of 63 CANopen slaves.

2. The size of the configuration file (.prm) of each BMECXM module is limited to 64 Kb maximum.

3. Each BMECXM module on the Ethernet bus communicates with the CPU. They are in the same network. Transparency is thus provided from the CPU or any PC connected on the same subnet up to the BMECXM module.

NOTE: No communication is possible between two BMECXM modules.
