Operator Interface Tech Note 24 - TNOI24

Abstract

This technical note presents how to connect a Red Lion G3 HMI with a Mitsubishi Q series PLC. The same setup can be used to program a Modular Controller Enhanced Master.

Products

Red Lion Controls CR1000 Human Machine Interface (HMI), CR3000 HMI, DA Series Data Station, Data Station Plus (DSP), G3 HMI, G3 Kadet HMI, Graphite® Controller, Graphite HMI, Modular Controller (MC), and ProducTVity Station™ (PTV)

System Diagram

See Figure 1:

Figure 1.

Cable Information:

Refer to Figure 2 for the RS232 Communication port information for the Mitsubishi QJ71C24N-R2 module:

Figure 2.

Communication cable CBLMIT03 from Red Lion Controls can be used to connect a G3 (or Enhanced Master or Data Station) RS232 port to the Mitsubishi QJ71C24N-R2 communication card.

Figure 3 presents the communication cable pinout between the Enhanced master and the QJ71C24N-R2 Communication card:

Information on the cable is available here: http://www.redlion.net/Support/Cable/CBLMIT03.pdf

Crimson Communication Setup:

RS232 Comms Port (as shown in Figure 4.)

- Driver on RS232 Comms port: Mitsubishi A/Q/FX Series PLC – MELSEC
- Frame Validation: No
- Baud Rate: 9600
- Data Bits: 8 bits
- Stop Bits: One
- Parity: Odd

Figure 4.

Comms Device (PLC11 as shown in Figure 5.)

- Drop Number: 0
- Melsec Control Format: Melsec1

Mitsubishi GX Developer Settings

Figure 6 shows the communication settings in Gx Developer environment. Fig.5 and 6
are part of Fig.4 showing the windows to access the QJ71C24-R2 settings. In this example, the
communication card is available in slot 9. 

To Access the Settings

- Click on “PLC Parameter” from the side menu,
- Choose the “I/O Assignment” tab,
- Check if the communication module is present in the slot you want,
- Click on “Switch Setting” to set up the module.

Switch Setting Explanations in GX Developer

Switch 1 and 2 are configuring Com port 1 settings. Therefore, Switch 3 and 4 refer to Com port 2 settings. In this example, the switch settings are:

- Switch 1 - 05C6
- Switch 2 - 0001

Explanation for switch 1:

- 05 means 9600 baud rate.
- C6 is explained in Figure 7.

Figure 7.

Bit 0 = Independent Control of the port
Bit 1 = 8 data bits
Bit 2 = yes to parity
Bit 3 = Odd parity
Bit 4 = 1 stop bit
Bit 5 = no checksum
Bit 6 = Write during run enabled
Bit 7 = Change setting enabled

NOTE:  Frame Validation (Red Lion) and Checksum (Mitsubishi) are the same. Please set accordingly.
