Command
TMR 16-bit timer
Operand
When the TMR command is executed, the designated timer coil will be electrified, and
the timer will begin timing. The contact's action will be as follows when the timing
value reaches the designated set value (timing value >= set value):
NO (Normally Open) contact
NC (Normally Close) contact
If the RST command has not been executed, the status of the designated element will
remain unchanged.

Command
CNT 16-bit counter
Operand
When the CNT command is executed from Off→On, this indicates that the designated
counter coil goes from no power → electrified, and 1 will be added to the counter's
count value; when the count reaches the designated value (count value = set value),
the contact will have the following action:
NO (Normally Open) contact
NC (Normally Close) contact
After the count value has been reached, the contact and count value will both remain
unchanged even if there is continued count pulse input. Please use the RST
command if you wish to restart or clear the count.

Command
MC/MCR Connect/release a common series contact
Operand N0–N7
MC is the main control initiation command, and any commands between MC and
MCR will be executed normally. When the MC command is Off, any commands
between MC and MCR will act as follows:
Determination of commands
Coil driven by OUT command None receive power
Elements driven by SET, RST
Applications commands
MCR is the main control stop command, and is placed at the end of the main control program.
There may not be any contact commands before the MCR command.
The MC-MCR main control program commands support a nested program structure with a
maximum only 8 levels; use in the order N0–N7, please refer to the following program:
T-K T0–T159, K0–K32,767
T-D T0–T159, D0–D399
TMR T5
