HMI Module
An optional HMI module can be installed on the HMI base module mounted next to the Web server CPU module. The
HMI module makes it possible to manipulate the RAM data in the CPU module without using WindLDR.
Communication Adapter and Module
The Web server CPU module can be used with an optional RS232C or RS485 communication module to add
communication port 2. With an optional HMI base module mounted with a slim type CPU module, an optional RS232C or
RS485 communication adapter can also be installed on the HMI base module.
RS485 communication adapter or module is installed to use Data link communication, Modbus communication, or user
communication. RS232C communication adapter or module is installed when the Web server CPU module communicates
with the devices that have RS232C communication port.
Analog I/O Modules
The analog input channel can accept either voltage (0 to 10V DC) and current (4 to 20 mA) signals or thermocouple (types
K, J, and T) and resistance thermometer (Pt100, Pt1000, Ni100, and Ni1000) signals. The output channel generates
voltage (0 to 10V DC or –10 to +10V DC) and current (4 to 20 mA) signals.
AS-Interface Master Module
One or two AS-Interface master modules can be mounted to communicate with a maximum of 124 slaves, or 496 inputs
and 372 outputs, such as actuators and sensors, through the AS-Interface bus.
PID Module
Two PID loops can be added per PID module. A maximum of seven PID modules (14 PID loops) can be connected.
Expansion RS232C/RS485 Communication Module
The Web server CPU module can be used with a maximum of five expansion RS232C/RS485 communication modules to
expand up to seven communication ports. Expansion RS232C/RS485 communication modules can be used for computer
link communication, user communication, data link, and Modbus communication.
Abundance of I/O Points
The I/O points can be expanded to a maximum of 492 I/O.
Safety and High Quality
The Web server CPU module maintains the safety and high quality that conforms to international standards, enabling the
Web server CPU module to be used in various areas of the world.
