DESCRIPTION



MOD-MUX is an innovative modular I/O system which provides a simple low cost solution for distributed I/O requirements. The MOD-MUX system consists of stand-alone Digital and Analog Input and Output modules which are connected together on a RS485 two wire multi-drop network using the MODBUS protocol. Two baud rates are selectable, 9600 and 19200 baud. Typical response times are under 50ms.

All MOD-MUX modules plug into industry standard DIN rail mount 11 pin relay bases. All modules have a minimum isolation of 1000VAC rms between the field and logic.

There are a number of configurations in which the MOD-MUX modules may be used in a system. Some are listed as follows:

A. Simple Point to Point I/O.

This is the basic configuration were a maximum of 8 Digital or Analog Inputs will be transmitted to 8 Digital or Analog Outputs at a remote location on the network. The primary advantage of this configuration is cost saving where 9 wires are replaced by a single twisted pair. It may also be used on existing installations to avoid having to install additional cabling for expansion purposes.
B. Complex Point to Point I/O.

This configuration allows for a larger number of I/O to be connected to the network at random
points on the network. A maximum of 32 Digital Input Modules and 16 Analog Modules may
be placed on the network, and the inputs are transmitted to a corresponding number of
Digital or Analog Output Modules. In this configuration the Modules are set to operate in
the MODBUS Slave mode and a Master Module called an I/O MAPPER is used to transmit
the Inputs from the Input Modules to the Outputs on the Output Modules.
 

C. I/O Expansion.
There are a number of devices such as PLC s (Programmable Logic Controllers) which have
a MODBUS Communications facility available. When configured as a MODBUS Master, and
attached to the RS485 network, MOD-MUX Modules may be used as remote I/O reducing
cabling costs and increasing the I/O capability of the PLC.
 

D. Data Acquisition.

Another use of the MOD-MUX Modules is for Data Acquisition where a PC (Personal
Computer) is connected to the Network. Many SCADA software packages support the
MODBUS Master Protocol and can hence retrieve data from Input Modules or send data to
Output Modules. The serial port of the PC is connected to an RS232/RS485 Converter
which in turn is connected to the Network.
