Transducer Block I/O Channels
The following section defines the Transducer Block I/O channels available for use by the function blocks.
The transducer block for the MX/QX PB is located in Slot 9 of the device. Standard parameters start
at Index 16 of the slot. Manufacturer-specific parameters begin with an offset index of 80; therefore,
these parameters begin at index 96.
Transducer blocks are referenced by channel numbers. The references are parameters of the function
block and are used to logically associate transducer and function block information. During block
configuration, the value of the transducer block channel number may be configured for input and
output function blocks.
All I/O channels contain one byte for Status.
Channel Channel Name Description
344 AO_CTRL_VALVE_FLOW_CHAN Desired valve position %
347 DI_POSITION_AND_BUS_MODE_CHAN Valve status and control mode
348 DI_POSITION_CHAN Valve status, moving/stopped
349 DI_ACTUATOR_FAULTS_1_CHAN Mechanical and electrical faults 1
350 DI_ACTUATOR_FAULTS_2_CHAN Mechanical and electrical faults 2
351 DI_ACTUATOR_ALARMS_CHAN Emergency shutdown and inhibits
352 DI_DISC_USER_INPUT_CHAN Discrete input from user
353 DI_READ_DISC_OUTPUT_CHAN Read discrete output
354 DO_POSITION_CHAN Command Stop/Open/Close
355 DO_ESD_CHAN Command Emergency Shutdown
356 DO_RELAY_CHAN Command Energize Relays
357 AI_POSITION_CHAN Current valve position (0-100%)
358 AI_ANALOG_INPUT_1_CHAN Value of analog input 1 (0-100%)
359 AI_ANALOG_INPUT_2_CHAN Value of analog input 2 (0-100%)
The actuator PROFIBUS control contains four discrete input (DI) bocks. However, as described below,
there are seven DI channels to choose from, so three channels are inactive.
Details of the channels are shown in the following tables.
