Special Diagnostic Auxiliary Relays
A PLC has a number of special auxiliary relays. These relays all have specific functions and
are classified into the following two types.
Special Single Operation Pulse Relays
When used with the pulse contacts LDP, LDF, etc., M devices in the range M2800 to M3072
have a special meaning. With these devices, only the next pulse contact instruction after the
device coil is activated.
Turning ON X0 causes M0 to turn ON.
