Description
CIO 0101 and CIO 0100 will be decremented by –1 every 0.1 s. If the PV reaches
0000 0000, the Completion Flag (CIO 015000) will turn ON. If CIO 000000 turns
OFF, the PV will again be set to the SV.

The following figure illustrates the relationship between the execution condition
for a long timer with a SV of 0086400.0 s (1 day), its PV, and the Completion Flag
assigned to it.

MTIM(122) is an accumulative timer that can have up to eight pairs of set values
and Completion Flags. Unlike most timer instructions, MTIM(122) is not defined
using a timer number and timer numbers are not needed to access the Comple-
tion Flags and PV. The timer is activated when the MTIM(122) execution condi-
tion is ON and the reset bit (bit 08 of D
Once activated, MTIM(122) increments the content of D
units of 0.1 second. If the PV reaches 999.9 s, it continues counting from 000.0,
and all Completion Flags are reset to zero. MTIM(122) accuracy is +0.0/–0.1 se-
cond.
Each time the instruction is executed, the PV (content of D

greater accuracy, the same MTIM(122) instruction can be input into the program
several times so the PV:SV comparison is made more frequently.
The timer can be reset by turning ON the reset bit (bit 08 of D
PV and all Completion Flags to zero. Counting resumes from zero when the re-
set bit is turned OFF if the instruction execution condition is ON.
The pause bit (bit 09 of D
the status of the PV and Completion Flags. The MTIM(122) instruction is treated
as a NOP(000) instruction when the pause bit is ON and the reset bit is OFF.
When the pause bit is turned OFF, counting resumes from the previous PV.
