Function
Cycle Time Settings (DM 6615 to DM 6619)
The following settings are effective after transfer to the PLC the next time operation is started.
DM 6615
00 to 15
Not used.
DM 6616
00 to 07
Servicing time for RS-232C port (Effective when bits 08 to 15 are set to 01.)
00 to 99 (BCD): Percentage of cycle time used to service RS-232C port.
08 to 15
RS-232C port servicing setting enable
00: 5% of the cycle time
01: Use time in bits 00 to 07.
DM 6617
00 to 07
Servicing time for peripheral port (Effective when bits 08 to 15 are set to 01.)
00 to 99 (BCD): Percentage of cycle time used to service peripheral.
08 to 15
Peripheral port servicing setting enable
00: 5% of the cycle time
01: Use time in bits 00 to 07.
DM 6618
00 to 07

00 to 99 (BCD): Setting (See bits 08 to 15, below.)
A fatal error will be generated and PLC operation will stop if the cycle time exceeds the cycle
monitor time set here.
08 to 15
Cycle monitor enable (Setting in 00 to 07
