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.
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)
See Figure 1:
Figure 1.
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:
Figure 3.
Information on the cable is available here: http://www.redlion.net/Support/Cable/CBLMIT03.pdf
- 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.
- Drop Number: 0
- Melsec Control Format: Melsec1
Figure 5.
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.
- 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.
Figure 6.
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.
