What is a synchorscope? From the name it sounds like some kind of synchronization. Two T100MD88+ PLCs can be connected together using either directly I/O handshaking or via the RS485 interface. When using RS485 the master PLC need to send serial command to the slave PLC. You can either use the NETCMD$ command or READMODBUS, WRITEMODBUS TBASIC command to achieve the communication. Some transmission delay is expected when the two PLCs are connected serially so two PLCs can't be perfectly synchronized in their actions due to this delay.
