COMMAND
[Function]
This signal informs that M, S, T or B (2nd miscellaneous function) command is given on the setting
and display unit.
With the signal, user PLC discriminates the command from that given in normal automatic
operation.
[Operation]
The signal turns ON when M, S, T or B signal is specified on the setting and display unit in manual
or automatic operation (other than auto start). Like "M function strobe" signal, the signal turns OFF
when "M function finish 1 or 2" signal turns ON, or in case of reset.
