CC-Link REGISTER ACCESS SETTING
RGTR.
PARAMETER
4943
Deactivate CC-Link register writing protection
Writing a preset passcode in this register deactivates the writing protection via CC-Link.
When the CC-Link passcode set in this register matches the preset one, setting ‘1’ or ‘2’ in the register address 4945
becomes available to enable writing in CC-Link registers.
Reading out the register value is not possible. It reads always ‘-1’ regardless of the code setting.
After writing is complete, be sure to set a value other than the passcode (‘0’ is recommended) to activate the writing
protection again.
4945
CC-Link register access setting
0 : Write disable (*)
1 : Write enable
2 : Write enable the count values
Other : Write disable
This setting is erased when the power supply to the unit is removed. It always starts with ‘0’ (Write disable) when the
power supply is turned on. Set ‘1’ or ‘2’ before starting writing at other registers.
In order to write a count value (e.g. active energy), set ‘2’ at this register. When it is set, the unit stops counting so that
a new count value can be written in the register. Be careful to use ‘2’ setting because no counting will be performed if
the unit remains with this setting.
When the CC-Link register writing protection is enabled, this register setting cannot be changed from ‘0’ to ‘1’ or ‘2’ un-
less a correct security code is set in the register 4943.
