Detailed Description of the Module
3.3
I/O Signals for the Programmable Controller CPU
3.3.1
List of I/O signals
Note that the I/O numbers (X/Y) shown in this section and thereafter depend on the mounting posi-
tion resp. on the start I/O number or head address of the ME3CAN1-L. This head address has to be
added to the shown I/O numbers.
For example, if the ME3CAN1-L occupies the range from X/Y040 to X/Y05F the head address is X/Y040.
However the least significant digit is omitted and the head address "n" in this case reads as "4". The "mod-
ule ready" input (Xn0) will be X40 and the "EMCY message available" signal (X(n+1)1) will be X51.

NOTE
The "Use prohibited" signals cannot be used by the user since they are for system use only.
If these are turned ON/OFF by the sequence program, the performance of the CANopen€ module
cannot be guaranteed.
