Abbreviation for PLC Editor: EM (END OF MODULE)
Execution time [µs] 2.0

command in a Module initiates the return jump to the Call Module (CM, CMT, CMF). The program is
continued with the instruction following the Call Module. The command EM is handled as program
end criterion; thus subsequent program instructions can be reached using a jump address.

Execution time [µs] 0
Number of bytes 0
Operands: 0 to 511

labels may be allocated addresses in the range 0 to 511.
