Communications and Cycle Time Settings (DM 6613 to DM 6619)
The following settings are accessed only once when program execution begins.
DM 6613 00 to 07 Servicing time for Communications Board port B
(effective when bits 08 to 15 are set to 01)
00 to 99 (BCD): Percentage of cycle time used to service port B.
Minimum: 0.26 ms; maximum 58.254 ms
08 to 15 Communications Board port B servicing setting enable
00: Do not set service time (Fixed at 5%, 0.26 ms min.)
01: Use time in 00 to 07.
Service time is 10 ms when operation is stopped, regardless of this setting.
Use DM 1000 through DM 2599 for the initial data area for the Special
I/O Unit Area.
• Data in the Special I/O Unit Area can be read/written.
• The data cannot be converted to ROM.
Transfer the contents of DM 7000 through DM 7999 to DM 1000
through DM 1999 at startup and use DM 1000 through DM 1999.
• The UM Area Allocation operation must be performed beforehand.
• The data is compatible with C200H applications that use EEPROM/
EPROM.
• ROM conversion is possible indirectly by writing DM 7000 through DM
7999 to ROM.
Use DM 7000 through DM 7999 for the initial data area for Special I/O
Unit Area.
• The UM Area Allocation operation must be performed beforehand.
• DM 1000 through DM 1999 can be used as regular DM.
• DM 7000 through DM 7999 can be converted to ROM.
Transfer the contents of DM 7000 through DM 8599 to DM 1000
through DM 2599 at startup and use DM 1000 through DM 2599.
• The UM Area Allocation operation must be performed beforehand.
• ROM conversion is possible indirectly by converting DM 7000 through
DM 8599 to ROM.
Use DM 7000 through DM 8599 for the Special I/O Unit Area.
• The UM Area Allocation operation must be performed beforehand.
• DM 1000 through DM 2599 can be used as regular DM.
• DM 7000 through DM 8599 can be converted to ROM.
