9.2 CIM configuration register block
Registers in this block can be read by means of function codes
0x03 and/or 0x04. They can be written as holding registers with
function codes 0x06 and 0x10.

00001
SlaveMinimumReplyDelay
The minimum reply delay from the slave in ms.
Value range: 0-10000, i.e. a reply delay of up to 10 seconds. This delay
is typically used in conjunction with a radio modem. The delay value is
stored in the device and will remain after a power-off. The delay set here
will be added to the internal delay in the device.
Default setting: 0.

SoftwareDefinedModbusAddress
This register holds the active Modbus address. The default setting is
0xE7 (231), and there is normally no need to change this value.
Note:
For CIM 200 this value is used only when the transmission speed
is set to "Software-defined" on the DIP switches SW4 and SW5.
Otherwise, it will be ignored by the slave.

00004
SoftwareDefinedBitRate
Modbus software-defined transmission speed enumeration.
The software-defined transmission speed value is stored in the device
and will remain after a power-off.
0: 1200 bits/s
1: 2400 bits/s
2: 4800 bits/s
3: 9600 bits/s
4: 19200 bits/s
5: 38400 bits/s.
Note:
This value is used only when the transmission speed is set to
"Software-defined" on the DIP switches SW4 and SW5. Otherwise, it will
be ignored by the slave.

00005
AutoAckControlBits
Used to select the behaviour of control bit acknowledgements from the
CIM.
0: Disabled.
Control bits are not automatically lowered when accepted by the device.
The user must lower the triggered control bit manually before the control
bit can be triggered again.
1: Enabled.
Control bits are automatically lowered when accepted by the device.
The user does not have to lower it manually (default].

00006
ReadWriteSeparation
Used to select value read-back behaviour.
The value in this register is stored in the device and will remain after a
power-off.
0: Register values can be written by both the Modbus master and the
CIM 250 (default).
1: Read-backs are put into separate registers by the CIM 250, hence
separating inputs from outputs.

00007
ScadaCallBackRegister
Used to select the register in the SCADA system that will be written
when a call-back request is sent via GPRS. See fig.
●

-
00008
NoDataActivityTimeout
The elapsed time with no data activity before the module issues a
"GPRS restart".

-
00009
SoftwareDefinedParity
Parity setting to be used when using "software-defined" settings.
0: No parity (default)
1: Even parity
2: Odd parity.
Note:
For CIM 200 this value is used only when the transmission speed
is set to "Software-defined" on the DIP switches SW4 and SW5.
Otherwise, it will be ignored by the slave.

-
00010
SoftwareDefinedStopBit
Stop bit setting to be used when using "software-defined" settings.
0: No stop bit
1: 1 stop bit (default)
2: 2 stop bits.
Note:
For CIM 200 this value is used only when the transmission speed
is set to "Software-defined" on the DIP switches SW4 and SW5 by
selecting a value outside the range [0; 247]. Otherwise, it will be ignored
by the slave.
