9.2.2 Connecting to the Network
After an AH500 series CPU module is set through HWCONFIG in ISPSoft, AH10/15EN-5A can carry
out communication. The basic setting of the CPU module is accomplished through the
RS-232/USB/Ethernet port. After IP addresses and subnet masks are assigned to AH10/15EN-5A,
and a network cable is connected to AH10/15EN-5A, AH10/15EN-5A can carry out the
communication. Users can choose a Cat 5e twisted pair cable as the network cable, and does not
need a jumper wire.
AH10/15EN-5A is equipped with two RJ45 ports. The ports function as a switching hub that
connects network segments. If users want to use these ports, they must assign a single IP address.
If AH10/15EN-5A is connected to two different networks, the users must disable the switching hub
function through HWCONFIG, and assign two IP addresses and two subnet masks to
AH10/15EN-5A so that AH10/15EN-5A connects to a wide area network (WAN) and a local area
network (LAN).
9.3 Registers
There are input registers, output registers, and control registers in AH10/15EN-5A. The status of
AH10/15EN-5A is stored in an input register, functions are triggered by the values in output registers,
and parameters related to communication are stored in control registers. Users can set input
devices and output devices in a CPU module which correspond to the input registers and the output
registers in AH10/15EN-5A through HWCONFIG in ISPSoft. Besides, the users can read data from
a control register by the instruction FROM, and write data into a control register by the instruction
TO. The functions of the registers are described below.
