    Pakscan IIE System Manual Integral type field control units mounted within a Rotork actuator electrical housing such as the IQ, IQT or Q range actuator. Externally mounted field control unit. Various packages are available, including 'Pakbox', weather-proof box, or rack mounting. The unit may be used for either actuator control applications, or for general purpose applications such as pumps, blenders etc.

  • Page 19: Functions

    Fig 4: Loopback system 5.2 Current Loop Start Up Operations The Pakscan IIE controls the current on the loop to communicate with the attached field units. Loop communication divides into two parts: configuration (when the master station decides whether the loop is complete, and if not, where the faults are), and normal operation.

  • Page 20: Loop Configuration

    Pakscan IIE System Manual 5.2.1 Loop Configuration The loop configuration phase is entered after power-up, after a loop fault is detected, or after a loop configure command is received. Configuration consists of the following steps: Wait for all the field units to go into loopback. The time is dependent on the baud rate.

  • Page 21: Modbus Serial And Ethernet Interfaces

    5.3 Modbus Serial and Ethernet Interfaces The Pakscan IIE master station is provided with two interfaces for data exchange with external host systems. These may be a combination of one serial and one Ethernet, two serial or two Ethernet connections.
