9.3 CIM status register block
Registers in this block can be read by means of function codes 0x03 and/or 0x04. They are read-only. Use this block for various kinds of
fault finding.
00008 NoDataActivityTimeout
The elapsed time with no data activity before the module issues a
restart of the APN connection.
-●-
00009 SoftwareDefinedParity
Parity setting when using software-defined settings.
0: No parity (default)
1: Even parity
2: Odd parity.
Note that for CIM 200, this value is used only when you set the
transmission speed to "software-defined" on DIP switches SW4 and
SW5. Otherwise, CIM 200 ignores it.
●--
00010 SoftwareDefinedStopBit
Stop bit setting when using software-defined settings.
0: No stop bit
1: 1 stop bit (default)
2: 2 stop bits.
Note that for CIM 200, this value is used only when you set the
transmission speed to "software-defined" on DIP switches SW4 and
SW5. Otherwise, CIM 200 ignores it.
●--
00011 ScadaPinCode
PIN code for SCADA systems, etc.
If GeneralStatus.ScadaPinCodeEnabled (register 00029, bit 0) is
enabled, enter the correct PIN code in this register in order to gain
access to remote control and configuration.
Verify acceptance in GeneralStatus.WriteAccess (register 00029, bit
1).
You programme the SCADA PIN code via the SMS command
"SETSCADACODE". See "CIM 260 SMS commands", which you can
download from Grundfos Product Center.

00012 Watchdog
Configuration of fieldbus communication watchdog.
0: Watchdog is disabled (default)
1: Watchdog is enabled, timeout 5 s.
Any other value disables the watchdog.
Watchdog action: The pump will be set to Local mode.
CIM 200: Watchdog is fed whenever serial line data appears on the
network. It is not a requirement that valid Modbus telegrams are preset
nor that CIM 200 is specifically addressed. An interruption of serial
data for more than 5 seconds activates the watchdog.
CIM 500: Watchdog is only fed if CIM 500 is specifically addressed with
Modbus TCP telegrams, matching IP address. If CIM 500 is connected
to a Modbus TCP network but never gets addressed, it will activate
watchdog after 5 seconds.
●-●
00013 GENIbusDiodeOff
For disabling the GENIbus LED2.
0: GENIbus diode LED2 has normal function.
1: GENIbus diode LED2 is permanently switched off.
