Chapter 4 Detailed Descriptions of the Fieldbus Network Adapters
4.4.12 0x101C – 0x101F Collective Process Message for I/O Modules
If a process alarm is activated (register 0x1133) and there is an alarm for a module, this is indicated
here with a set bit. A module's slot position corresponds to its position in the 64-bit data field (minus
passive modules without slot recognition). Example: 0x0000 0000 0000 0002 = There is a process
alarm for module 2.
Reading the module's process alarm memory (0xBXXX) confirms the alarm and resets the
corresponding bit. In case of multiple process alarms for one module, only the latest alarm is
displayed. The next alarm is then placed in a wait loop and only becomes active once the current one
has been confirmed.
4.4.13 0x1028 – 0x102F Module Status
The module status (2 bits per module) is displayed in the corresponding bit positions of the 128 bits.
0 0 Valid data from this module
0 1 Invalid data, faulty module
1 0 Invalid data, incorrect module
1 1 Invalid data, missing module
4.4.14 0x1030 MODBUS DATA EXCHANGE Watchdog, Current Time
Amount of time (input value * 10 ms) still remaining on the active watchdog to monitor the exchange
of process data. If a 0 is read, the watchdog has expired and must be restarted.
If 0xFFFF is read, the watchdog is deactivated.
4.4.15 0x1120 MODBUS DATA EXCHANGE watchdog, predefined time
In this register, the watchdog is activated/deactivated and the watchdog time is set. Process date
can be exchanged as long as the watchdog is deactivated or it is activated and still running. But it is
accepted only after a watchdog reset to the current time. The length is calculated with the input
value * 10 ms. Entering 0 deactivates the watchdog.
4.4.16 0x1121 MODBUS DATA EXCHANGE Watchdog Reset Register
If Bit 0 in this register is set, the predefined time is loaded into the watchdog time (watchdog reset).
If Bit 8 in this register is set, an expired watchdog (value 0 in register 1030) is reactivated.
4.4.17 0x1122 Lock force Mode on Web Server
In default setting the force mode can be enabled via the web server (after Login). The force mode can
be locked by writing the double word "LOCK" (0x4C4F, 0x434B). Writing of "FREE" (0x4652, 0x4545) will
unlock the force mode again.
