Table 214: 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.
10.5.6 MODBUS Constants Registers
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.
10.5.6.1 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.
10.5.6.2 Register 0x2010 – Revision (Firmware Index)
This register provides the consecutive revision index (firmware index) for the
controller.
Example: 5 for Version 5.
10.5.6.3 Register 0x2011 – Series Designator
This register provides the designation (ID) for the WAGO series (Series Code) for
the controller.
Example: 750 for WAGO-I/O SYSTEM 750.
10.5.6.4 Register 0x2012 – Device ID
This register provides the device ID (WAGO Item No.) of the controller.
Example: 8206.
