The tables below show special auxiliary relays and special data registers used in CF-ADP instructions
(FNC300 (FLCRT) to FNC305 (FLSTRD)).
1. Special auxiliary relays R: Read only W: Write only R/W: Read or Write
*1. Cleared when the PLC mode is changed from STOP to RUN.
*2. When an instruction for the CF-ADP is driven while the system is updating the status of special data
registers, execution of the instruction for the CF-ADP may be delayed by several scans. If this delay is
regarded as a problem, use this flag to stop the updating of the status.
2. Special data registers R: Read only W: Write only R/W: Read or Write
*1. Cleared when the PLC mode is changed from STOP to RUN.
