2.6.3 Expansion Unit
GP-4301T/TW is not equipped with an expansion unit interface. The expansion unit
(each kind of unit like CC-LINK Unit) for GP-2300 series cannot be used.
2.6.4 Isolation Unit
The isolation unit for GP-2300 series (CA2-ISOALL232-01, CA2-ISOALL422-01)
cannot be used for GP-4301T/TW. You can use the RS-232C isolation unit for
GP-4301T/TW (CA3-ISO232-01) instead. In this case, select “VCC” from [System
Settings] -> [Device/PLC] in the [Project] menu on GP-Pro EX.
2.7 Power Connector
The power connector on GP-4301T/TW is a spring lock type. If you replace GP-2300
series with GP-4301T/TW, change the power cable.
2.8 Backup Battery (only when replacing with GP-4301T)
Unlike GP-2300 series, GP-4301T does not use rechargeable secondary batteries but
replaceable primary ones. (For both a rechargeable type and a replaceable one,
contents to be backed up are the same.)
When the time for replacement of backup batteries approaches, the message to urge
you to replace the battery, “RAAA053: Running out of power in the backup battery.
Please change the battery.” appears. When the message appears, replace the battery
referring to the GP4000 series hardware manual.
