The maximum allowable field wiring resistance between the transmitter and the IOTA connection terminal is dependent upon the voltage requirement of the transmitter. The formula for calculating the maximum wiring resistance for the Series C UIO channel used as an analog input is given by the following equation.
Setting an SLC address for a Single Point Module
Each module can be set to one of 159 addresses (01-159) and is factory preset with an address of “00”.
To set an SLC address, use a screwdriver to adjust the rotary switches on the module to the desired address. The module below is set at
“35”. When finished, mark the address on the module face in the place provided.
5.2.2 Setting an SLC address for a Multi-Point Module
The SLC address of a multi-point module is set in the same fashion as a single-point module.
In Class B operation, each MMF-300-10, MMF-302-6, CMF-300-6, and CRF-300-6 module is set to a base address. The remaining
module points are automatically assigned to the next higher SLC addresses. For example, if the base address of an MMF-300-10 is set to
28, the next module points will be addressed to 29, 30, 31, 32, 33, 34, 35, 36 and 37.
In Class A operation, alternate module points are paired together, resulting in a total of five module points. For example, if the base
address of an MMF-300-10 is set to 28, then 30, 32, 34 and 36 will be automatically assigned to the remaining module points and 29, 31,
33, 35 and 37 are available for use by other modules.
To set an SLC address, use a common screwdriver to adjust the rotary switches on the module to the desired address. The module below
is set at “28”.
NOTE: The MS-9050UD and ES-50X can support addresses 01 - 50. The MS-9200, MS-9200UD, MS-9200UDLS, and ES-200X, can
support module addresses of 01 - 99. The MS-9600, MS-9600LS, and MS-9600UDLS can support module addresses 01 - 159. The plastic
stop located on the Tens switch must be removed to set addresses above 99.
