2. COM1 functions as a slave station. It can be connected to a human-machine interface.
2.3.2 COM2 (RS-485 Port)
1. COM2 is an RS-485 port. It can function as a master station or a slave station. The communication
protocols that COM2 supports are Modbus ASCII and Modbus RTU, and the transmission rate
supported is in the range of 9,600 bps to 115,200 bps.
2.
COM2 can function as a master station or a slave station. If it functions as a master station, it can be
connected to a Delta PLC, or an inferior drive such as a Delta servo drive, a Delta AC motor drive, or a
temperature controller, and read/write data. If it functions as a slave station, it can be connected to a
human-machine interface such as a Delta TP series HMI or DOP series HMI.
2.3.3 COM3 (RS-232/RS-485 Port)
1. If COM1 (RS-232 port) and COM2 (RS-485 port) can not fulfill a communication requirement, users
can use the function card DVP-F232S or DVP-F485S to add a communication interface called COM3
(RS-232/RS485 interface). The functions of DVP-F232S/DVP-F485S is the same as those of COM1,
but the transmission rate that DVP-F232S/DVP-F485 supports is 9600/19200/38400 bps in an ASCII
mode.
2. COM3 functions as a slave station. It can be connected to a human-machine interface.
