Section 2-2
Note
(1) The function block capacity is not included in the program capacity.
(2) Can be used as Modbus-RTU easy master function.
Serial port (RS-232C ,
RS-422A/485)
Ports not provided as standard equipment. (EM-type CPU Unit: 2 ports max., EL-type CPU Unit: 1
port)
The following Option Boards can be mounted:
• CP1W-CIF01: One RS-232C port
• CP1W-CIF11/CIF12: One RS-422A/485 port
Applicable communications modes (same for all of the above ports): Host Link, NT Link (1: N
mode), No-protocol, Serial PLC Link Slave, Serial PLC Link Master, Serial Gateway (conversion to
CompoWay/F, conversion to Modbus-RTU), peripheral bus (See note 2.)

Accuracy (monthly deviation):
−
0.5 min to +4.5 min (ambient temperature: 55
°
C),
−
2.0 min to +2.0 min (ambient temperature: 25
°
C),

°
C)
Memory
Backup
Built-in flash
memory
User programs and parameters (such as the PLC Setup) are automatically saved to the flash
memory. It is also possible to save and read data memory initial data.
The data is automatically transferred to RAM when the power supply is turned ON. (Data memory
initial data, however, may or may not be transferred, depending on the selection in the PLC Setup.
Battery
backup
The HR Area, DM Area, and counter values (flags, PV) are backed up by a battery.
Battery model: CJ1W-BAT01 (Built into the CP1L-EL/EM CPU Unit.)
Maximum battery service life: 5 years
Guaranteed (ambient temperature: 55°C): 13,000 hours (approx. 1.5 years)
Effective value (ambient temperature: 25°C): 43,000 hours (approx. 5 years)
Memory Cassette
function
A CP1W-ME05M Memory Cassette (512K words, optional) can be mounted. It can be used to
back up the following data on the CPU Unit's RAM and to transfer the data at startup.
• Data saved on Memory Cassette: User programs, parameters (such as the PLC Setup), DM
Area, data memory initial data, comment memory (CX-Programmer conversion tables, com-
ments, program indices), and FB program memory.
• Writing to Memory Cassette: By operations from the CX-Programmer.
• Reading from Memory Cassette: At startup, or by operations from the CX-Programmer.
