CJ1-H/CJ1M CPU Unit Ver. 3.0 Upgrades Section 1-4
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.
Unit Ver. 3.0 or Later 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.
1-4-3 Comment Memory (in Internal Flash Memory)
Unit Ver. 2.0 or Earlier 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.
Unit Ver. 3.0 or Later 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-
able.
• Symbol table files (including CX-Programmer symbol names and I/O
comments)
• Comment files (CX-Programmer rung comments and other comments)
