Troubleshooting Connection Issue with Mitsubishi E1101 Touch Screen

Question:

As a newcomer to PLCs and HMIs, I am currently facing a challenge with connecting to my machine's E1101 Touch Screen. Despite my initial attempts using Mitsubishi GT Works3, I was unsuccessful in establishing a connection. After some research, I discovered that I needed to utilize Mitsubishi E-designer, which I already have. However, I am unsure about which port to use for the connection. I have tried using a USB A to B cable without success, as well as an RS-232 connection, but I am unsure how to initiate communication. It is worth noting that the machine also features a Mitsubishi Q series PLC.

Hey Achughes, have you managed to successfully connect the E1101 to your PC using RS232?

In the past, I utilized the HMI e1101 device with Ethernet connectivity for programming. To program this HMI, I utilized the E-designer software. In order to connect it with a Mitsubishi PLC, a mini din8-positions male connector on one end and a 25-positions D-sub male connector on the other end were used. Additionally, it is possible to connect your PC using the RS232 port.

To easily identify the IP address assigned to the HMI, power it up and observe the display for a few seconds. By default, the IP address is 192.168.1.1. Adjust your computer's IP address to match the same subnet. If the HMI is not password-protected, you can extract the project using E-Designer. Additionally, there is no need for a crossover cable as the port is Auto-MDIX and automatically detects the cable type.

Artmierz mentioned that he has used the HMI e1101 in the past. To program it, he utilized the Ethernet port and E-designer software. When connecting to a Mitsubishi PLC, one side used a mini DIN8-positions male connector, while the other side used a 25-positions D-sub male connector. Additionally, you can connect your PC via the RS232 port. Can you share where you obtained the trial version of E-designer?

If you are having trouble finding the E Designer software, which has been discontinued for some time now, consider reaching out to Beijers as they may have an alternative solution that is not too costly. The E series devices come equipped with two ports - a 9-pin port used for programming (232) and a 25-pin port with multiple connections for 485/422 (422 is mainly used for Mitsubishi products). Beijers also produced badge versions of the software for Mitsubishi devices. The 232 connection is straightforward, but it's important to note that pin configurations may have changed with the release of newer versions (e.g. from E900 to E1000 range), requiring a null modem adapter or a different pin layout. Using a serial connection initially is recommended as Ethernet connectivity may be tricky unless the Ethernet port is properly configured for data transmission. Additionally, if a password was set by the original programmer, there may be no way to recover the program. The most recent version of E Designer that I am aware of is version 7.xx.

You're on the right track with using E-designer for the E1101 HMI. Regarding the port, you should typically use RS-422 (serial). Identify which serial port you wish to use and ensure the settings on your serial port and E-designer match. The E1101 generally operates over a straight-through DB9 cable. As for your PLC connection, note that Q series PLC usually communicates via the front USB port (type B) or the Ethernet port. Also, you'd need GX Works2 or GX Works3 to program the Q series PLC. In your case, it might be best to troubleshoot these connections one at a time to minimize any potential confusion. Make sure your cable and software configurations are correct, and do verify if any firewalls might be interrupting the connection.

In my experience with Mitsubishi Q series PLC and E1101 touch screens, you may need to configure your RS-232 settings correctly in order to facilitate communication. Hopefully, you've got your RS-232 serial port set to 8 data bits, 1 stop bit and no parity, as this is the typical configuration. Also, review your PLC settings and ensure they match those in your E-Designer project, as inconsistencies could also prevent communication. Sometimes it can also be a simple case of either a bad cable or not having the right drivers installed, so perhaps consider checking those as well. There's a lot of troubleshooting to be done, but remember, start simple and work your way up. Good luck!
