MC 1E Binary master

Mitsubishi MC 1E binary protocol PLC address read and write driver

Open the plugin

Enter “Development Configuration → Collection Configuration”, create a device and select “Mc1E_BinaryMaster” in “Collection Plugin”.

Supported channels and data types

Channel typePre-configuration check
Serial PortConfirm that the serial port is not occupied by other programs and maintains the same baud rate, data bits, stop bits and parity bits as the device.
TCP ClientConfirm network reachability of the device IP, port, and gateway to the device.
TCP serverConfirm that the local listening address and port are available, and allow on-site devices to actively connect to the gateway.
UDPConfirm the local binding address, port and firewall rules, and check the source of the packet.

Optional data types: Boolean, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Float, Double, String, Decimal

This list describes types allowed by the plugin editor. Address width, arrays, string length and read/write restrictions still follow this page; it does not mean that every address supports every type.

Functions

FunctionPurpose
Read and writeRead a confirmed point and write only to an approved test point.
MessagesView sent and received frames, protocol fields, and error details.

Verify the configuration

Monitor D100 online in the PLC engineering tool, compare its value with the gateway variable and confirm advancing sample times.

Troubleshooting

  • Match frame generation, ASCII/binary encoding and device-area radix. 1E does not use 3E routing; R extension areas follow the table on this page.
  • The serial port device does not respond: Confirm that the serial port is not occupied, and check the baud rate, data bits, stop bits and parity bits.
