TC-net network data
The data source type is 61. TC net is an automated L1
high-speed communication network of TMEIC Corporation in
Two TC-net network cards can be inserted into a computer. After the computer is powered on, the green light should always be on. After Windows starts, SCset.exe initializes and enables the TC-net network card according to the configuration files card0. ini and card1.ini. After success, the TX yellow light should always be on, and online data will be written to the memory of this card. Otherwise, data will not be received.
The configuration files for the two cards are shown in the following figure:
Each network card needs to use a rotary switch to set the station address 01~FF, which cannot be repeated throughout the entire network. If the station address is set to 00, even if the Windows driver is installed, it will still display abnormalities and cannot function properly.
Each variable on TC-net has an address, and PDA reads and writes variables according to the address. The variable address table can be exported in the PLC program. An example of Config.csv configuration is as follows, where adr is the register address, 1 register has 2 bytes, and 0x40000 is the TC-net card memory size(byte). [1000,10CH,10.000ms,,61,Note,,,,,,,,0x40000] No,
