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. up to 10 seconds reply delay. This delay is
typically used in conjunction with a radio modem. The delay value is
stored in the device and remains after a power-off. The delay set here is
added to the internal delay in the device.
Default value is 0.

RegisterOffset
An address offset that is added to all addresses above 00100. Default
value is 0.
Note that this offset does not affect the CIM configuration register block
or the CIM status register block addresses. The register offset value is
stored in the device and remains after a power-off.
For most applications, this offset should not be changed.

00003
SoftwareDefinedModbusAddress
This register holds the active Modbus address. The default value is
0xE7 (231), and there is normally no need to change this value.
Note that 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, CIM 200 ignores it.

00004
SoftwareDefinedBitRate
Modbus software-defined transmission speed enumeration.
The software-defined transmission speed value is stored in the device
and remains 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 that this value is used only when the transmission speed is set to
"Software-defined" on the DIP switches SW4 and SW5. Otherwise, CIM
200 ignores it.

00005
AutoAckControlBits
Used to select the behaviour of control bit acknowledgements from the
CIM/CIU.
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 remains after a
power-off.
0: Register values can be written by both the Modbus master and the
CIM [default].
1: Read-backs are put into separate registers by the CIM, hence
separating inputs from outputs.

NoDataActivityTimeout
The elapsed time with no data activity before the module issues a restart
of the APN connection.

SoftwareDefinedParity
Parity setting to be used 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 the transmission
speed is set to "Software-defined" on the DIP switches SW4 and SW5.
Otherwise, CIM 200 ignores it.

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 that 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, CIM 200 ignores it.
