OPENNET CONTROLLER USER’S MANUAL 2-1
2: MODULE SPECIFICATIONS
Introduction
This chapter describes OpenNet Controller modules, parts names and specifications of each module.
Available modules include CPU modules, digital I/O modules, analog I/O modules, expansion power supply module,
remote I/O master module, and OpenNet interface modules such as DeviceNet slave and LONWORKS interface modules.
Analog I/O modules and OpenNet interface modules are also called functional modules. A maximum of seven functional
modules can be mounted with one CPU module.
CPU Module
The CPU modules are available in sink and source output types which have a transistor sink or source output of the high-
speed counter, respectively. Either type is available with or without a memory card connector. All CPU modules have two
RS232C ports and one RS485 port.
