2.3 Communication Ports

AH20MC-5A/AH10PM-5A/AH15PM-5A is equipped with a mini USB port and an Ethernet port.
Besides, AH20MC-5A is equipped with a DMCNET port. These ports are described below.
Mini USB: A mini USB port can function as a slave station. Users download or upload a program
through a mini USB port. The communication protocols a mini USB port supports are
Modbus ASCII and Modbus RTU.
Ethernet: An Ethernet port can function as a master station. The communication protocol it supports
is MODBUS TCP/IP.
DMCNET: A DMCNET port can be used to control a servo drive.
