9.5.4.5 Register 0x1104 – Watchdog Operation Mode
This register contains the value for the watchdog operation mode.
The register can be both read and written irrespective of the watchdog status.
The following operation modes are possible:
Table 224: Watchdog Operation Modes
Value
Name
Explanation
0x0000
STANDARD_
WATCHDOG
“Standard Watchdog” operation mode;
the watchdog must be controlled explicitly via
commands (see register 0x1100 Watchdog
Command).
0x0001
ALTERNATIVE_
WATCHDOG
“Alternative Watchdog” operation mode;
the watchdog is activated immediately with a
timeout > 0 s in register 0x1102 (Watchdog
Timeout). Each trigger restarts both the running
as well as the expired watchdog. In this
operation mode the registers 0x1102
(Watchdog Timeout) and 0x1103 (Watchdog
Config) are also saved retentively with the
operation mode itself. After a device restart, the
“Alternative Watchdog” operation mode is
retained with the same configuration as before
and is therefore immediately active again when
the timeout is set.
9.5.5

Registers 0x2000 … 0x2008 provide constants based on the table “WAGO
Modbus Registers”. It is possible to read all of the constants, or a consecutive
portion of them at once.
9.5.6
Electronic Nameplate
Registers 0x2010 to 0x2015 contain information from the electronic nameplate. It
is possible to read the entire nameplate or a consecutive portion of it all at once.

This register provides the consecutive revision index (firmware index) for the
controller.
Example: 5 for Version 5.
