AH500 Module Manual
9-2
9.1 Introduction
AH10/15EN-5A is an AH500 series Ethernet module. The data in an AH500 series CPU module can
be transmitted to a remote device through Ethernet. Besides, the CPU module can control the
remote device through ISPSoft, and a program can be downloaded to the CPU module through
ISPSoft.
9.1.1 Functions
There are two Ethernet ports. They can automatically detect whether the transmission speed is
10 Mbps or 100 Mbps.
Auto-MDI/MDIX
It supports the Modbus TCP protocol. (It supports a master mode and a slave mode
simultaneously.)
It supports the IEC60870-5-104 protocol (available for AH15EN-5A)
It supports EtherNet/IP protocol (available for AH10EN-5A V2.0)
Sending emails
It supports SNMPv1 and SNMPv2.
It automatically adjusts the real-time clock in an AH500 series CPU module through the Network
Time Protocol (NTP).
