The HMIGTO5310 (HMI-GTO-5310) is a Modicon Magelis GTO advanced touchscreen panel. It features a 10.4 inch display with a 96 MB flash memory. The panel uses an external power supply of 24 Volts DC, and has a lithium battery for internal RAM. It’s back light lifespan is 50,000 hours at 25 °C. Using an SDHC or SD card, one can add up to 32 GB of data storage to the HMIGTO5310. It also has an internal RAM of 512 kB used to back up data. Using either the panel’s software or its touch panels, a user can control 16 different levels of screen brightness.

The HMIGTO5310 weights precisely 2 kg. It measures 272.5 x 214.5 x 57 mm (W x H x D).  The HMIGTO5310 can be mounted by using 4 screw clamps with flush mounting.

The HMIGTO5310 supports a large number of downloadable protocols, including the Modbus TCP, Siemens Simatic, Rockwell Automation / Allen Bradley, Omron Sysmac, Mitsubish Melsec, FIPWAY, Modbus Plus, Uni-TE, and Modbus. The panel supports a number of integrated connection types, some of which include the Ethernet RJ45, the USB 2.0 ports, COM2 serial links, and a COM1 serial link.  When using the COM2 serial interface, be aware that the serial port is not isolated. The signal ground and frame ground terminals are connected inside the panel. There is risk of electric shock if precautions are not taken. When using the signal ground terminal to connect an external device to the panel, verify that a short circuit loop was not created when you set up the system. Connect the #8 signal ground terminal to remote equipment when the host PLC unit is not isolated. Connect the #8 signal ground terminal to a known reliable ground connection to reduce the risk of damaging the circuit.

When setting up RS-485 communication, the cable diagram for some equipment may require polarization on the terminal side. This terminal does not require any special setting as it handles polarization automatically.

The Schneider Electric / Modion HMI-STU-855 is a 5.7 inch touch panel screen with a Magelis operating system and CPU ARM9 processor. It uses a QVGA TFT color touchscreen with a pixel resolution of 320 x 240 pixels. It uses an external supply source of 24 volts and consumes 6.8 watts of power. It has 16 MB of application battery with 64 kB available to back up data. The HMISTU855 is able to download a number of protocols including Modbus, Modbus TCP/IP, Uni-TE, and 3rd party protocols.  When using the HMISTU855, all connections to the communication ports on the bottom and sides of the unit must not put large amounts of stress on the ports. Be sure to securely attach communication cables to the panel or cabinet. Use only RJ45 cables with a functioning locking tab.

Critical detected alarm indicators and systematic function require independent and redundant protection hardware or mechanical interlocks. It is important that when power is cycled, the user waits at least 10 seconds before restoring power. Switching the power on and off quickly can damage the unit. The interface is connected to remote equipment using a RS232C or RS-485 cable. The connector that is used is a RJ45-8 pin type. The using a long PLC cable to connect the unit, a difference of electric potential can be observed between the cable and the ground, even when connected to a ground. The serial port on the HMI-STU-855 is not isolated. The signal ground and frame ground terminals are connected inside the unit. When setting up the RS-485 communication, the cable diagram for some equipment may need polarization on the terminal side. This terminal does not need any special setting because it can handle polarization automatically.
