Function
Input bits can be allocated to Input Units or I/O Units. The 16
bits in IR 000 are always allocated to the CPU Unit's built-in
inputs.
Output bits can be allocated to Output Units or I/O Units.
Work bits do not have any specific function, and they can be
freely used within the program.
Used to indicate the Controller Link Data Link status infor-
mation. (Can be used as work bits when a Controller Link
Unit is not mounted.)
Used to indicate the Controller Link error and network partic-
ipation information. (Can be used as work bits when a Con-
troller Link Unit is not mounted.)
Used when the MACRO instruction, MCRO(99), is used.
(Can be used as work bits when the MACRO instruction is
not used.)
These bits are allocated to the Inner Board mounted in slot 1
of the CQM1H-CPU51/61. (Can be used as work bits when
the CQM1H-CPU11/CPU21 is being used or slot 1 is empty.)
CQM1H-CTB41 High-speed Counter Board:
IR 200 to IR 213 (14 words): Used by the Board
IR 214 and IR 215 (2 words): Not used.
CQM1H-SCB41 Serial Communications Board:
IR 200 to IR 207 (8 words): Used by the Board
IR 208 to IR 215 (8 words): Not used.
Used to store the analog settings when the CQM1H-AVB41
Analog Setting Board is mounted. (Can be used as work bits
when an Analog Setting Board is not mounted.)
Used to store the present values of the built-in high-speed
counter (high-speed counter 0). (Can be used as work bits
when high-speed counter 0 is not being used.)
