Description
In this case the watch dog signal (WD) of the K9203 appertain-ing central module will be switched off.
If systems with redundant central modules and a common I/O bus are used then the output modules are related to both central modules. In case of a fault both the watch dog signals of the central modules are switched off. That means all the I/O modules are switched off.
If systems with redundant central modules and redundant I/O bus are used then the output modules are related to one central module and one I/O bus. In case of a fault only the watch dog signal of the related central module is switched off. That means only the related I/O modules are switched off.
Switch off of the appertaining coupling module (IO-CON)
In this case the watch dog signal (WD) of the appertaining coupling module will be switched off. That means that all I/O modules related to this coupling module will be switched off.

All input/output modules can be used with both redundant and single channel models of the central devices.
– Microprocessor
– Flash-EPROMs of the program memory for the operating system and the user’s program usable for min. 100.000 writing cycles
– Data memory in sRAM
– Multiplexer to connect I/O bus, DPR and redundant CU (not used in the H51q-M system)
– Dual Port RAM for fast memory access to the second central module (not used in the H51q-M system)
– 2 interfaces RS 485 with galvanic isolation. Transmission rate: max. 57600 bps. Set to 9600 bps and to 57600 bps by switch, or setting also of other transmission rates by software (the software values have priority)
– Diagnostic display and 2 LEDs for information out of the system, I/O level and user`s program
– Power supply monitoring
– I/O-Bus logic for the connection to the input/output modules 55
– Hardware clock, battery backed
– Fail-safe watchdog
– Battery backup of the sRAMs via batteries on the central module with monitoring.
