Note Specific data could be shared without communications instructions if

user-specified CompoWay/F commands were not required, however,

by using the CJ1W-CIF21 Basic Communications Unit.

FINS commands (CompoWay/F commands encapsulated in FINS frames)

received by the CPU Unit at the built-in serial port (RS-232C port or peripheral

port) are converted automatically into CompoWay/F command frames and

transmitted on the serial line. This enables access to CompoWay/F-compati-

ble OMRON components that are connected to the CPU Unit's built-in serial

port via either an NS-series Programmable Terminal (PT) or by using the

CMND(490) instruction.

Comment data and section data could not be stored in the actual PLC when a

project was downloaded from the CX-Programmer to the CPU Unit unless

both a Memory Card and EM file memory were available.

A comment memory is provided within the CPU Unit's internal flash memory.

Therefore, the following comment/section data can be stored in and read from

comment memory even if neither Memory Card nor EM file memory are avail-

• Symbol table files (including CX-Programmer symbol names and I/O

• Comment files (CX-Programmer rung comments and other comments)

• Program index files (CX-Programmer section names, section comments,

and program comments)
