Process Solutions Automation Control PSC6194 Controller Readout and
Control System
Product Overview
To control the liquid and gas supply flows, Process Solutions Corp. offers a custom engineered solution consisting of a 4.3” color touchscreen PLC readout and control system. The touchscreen enables the user to easily view or change functions. The PSC6194 controller serves as a power supply unit, for up to two meters and two controllers, and comes equipped with Analog IOs and Modbus interface. The controller also provides data logging of instrument data.
Display

Model Key
The model key on the product label contains information about the technical
properties of the instrument as ordered. The specific properties can be
retrieved with the diagram below (Mini-Cori controller example).
Refer to the Communication (I/O) to determine if the Broncho’s instrument is
equipped with Modbus communication.
Analog Setup
Connecting Bronkhorst flow instruments to PSC controller via RS232, Channel 1
– 4. Bronkhorst instruments must be configured in Analog Mode to communicate
via RS232.
Modbus Setup
Connecting Bronkhorst flow instruments to PSC controller via RS485/Power. Bronkhorst instruments must be configured in Modbus Mode to communicate.
Communication settings are:
Baud rate: 38400 Parity: Even
Data Bit: 8
Stop Bit: 1| MFC#1: Address 1
MFC#2: Address 2
MFM#1: Address 3
MFM#2: Address 4
Configure Control Mode
To change Bronkhorst instrument from Analog to Modbus, or vice versa, the
control mode must be configured via FlowDDE
(https://www.bronkhorst.com/en-us/products-en/accessories-and-
software/flowware/flowdde/).
Connecting to FlowDDE
In the messages section the general procedure to start serving client
applications with the FlowDDE server is described in four steps:
- Connect an instrument to a COM port of the PC
- Set the communication settings
- Start the communication
- Press F3 or
- Communication tab > Open Communication
- Wait until FlowDDE is ready
- Message: “Server is active and ready for any client”
If further instruction is needed, please refer to the FlowDDE Manual found in the link above.
Analog to Modbus Configuration
After opening communication, use the following steps to change the Control
Mode from Analog operation to Modbus operation:
- FLOW-BUS tab > Test Flow-BUS and DDE
- Or Press F6
- Select the following parameters to view simultaneously
- Parameter 7 – InitReset
- Parameter 12 – IO Status
- Set parameter InitReset to 64 (unlocked)
- Read parameter IO Status
- Subtract 64 from the read value
- New Parameter Value: 15 or 11
- Write the new value to parameter IO Status
- Set parameter InitReset to 82 (locked)
- Restart Bronkhorst instrument
- InitReset must be unlocked/locked for the new Control Mode to remain after the instrument is restarted
Modbus to Analog Configuration
After opening communication, use the following steps to change the Control
Mode from Modbus operation to Analog operation:
- FLOW-BUS tab > Test Flow-BUS and DDE
- Or Press F6
- Select the following parameters to view simultaneously
- Parameter 7 – InitReset
- Parameter 12 – IO Status
- Set parameter InitReset to 64 (unlocked)
- Read parameter IO Status
- Add 64 from the read value
- New Parameter Value: 79
- Write the new value to parameter IO Status
- Set parameter InitReset to 82 (locked)
- Restart Bronkhorst instrument
- InitReset must be unlocked/locked for the new Control Mode to remain after the instrument is restarted
