5.4.15. Table [18]: Actuator System Type ID

Words [4

 63] PLC access: Read Only.

This data is primarily derived from holding registers [44] & [100] in the actuator. These registers are

retrieved with 2 separate Modbus read commands when the particular actuator is being polled

(scanned) during a diagnostic scan.

There are currently 4 types of EIM equipment identified. There are 6 system type values that can be

entered into table [18]:

• If EIM equipment type = 320A … value in table [18] = “1”

• If EIM equipment type = 320B … value in table [18] = “2”

• If EIM equipment type = TEC2000 … value in table [18] = “3”

• If non-EIM equipment type … value in table [18] = “0” or “255”

NOTE: There are 2 possible values if the unit is identified as non-EIM:

• 0 … If failed identification … method 1.

• 255 … If failed identification … method 2.

The 1746-C uses these values internally.
