I ENGINEERING UNIT CONVERSION

Engineering unit value °C or K is multiplied by 10 and expressed in 16 bits. °F data is represented in engineering unit

value, without multiplication. Engineering unit value A is multiplied by 100 or 1000, expressed in 16 bits. Negative value

is represented in 2 s complements.

■ COUNT VALUE

The count value is 32-bit data. It is divided in 2 words of 16 bits represented with 2 addresses.The lower address is

The maximum count value available is 1 000 - 4 294 967 295. In case of overflow, the vaule is reset to 0 or 1

(configurable) from which the count will restart. The preset of the count value is also available. Use the R7CON or

commands for the configuration.

EXTENSION MODULE

A ‘basic’ module can be attached with one ‘extension’ module. The extension module is powered from the basic module.

By combining two modules, single station can handle mixed analog and discrete signals, 32-point discrete inputs, 32-point

discrete outputs, 16-point discrete I/Os and other combinations of signals.

Note: Relay contact 8 points output module can not be attached with an ‘Extension’ module.

■ OUTPUT AT THE LOSS OF COMMUNICATION

The extension module is set to ‘Hold Output’ by factory default setting. The PC Configurator software is used to change the

setting to ‘Reset Output.’

CONNECTING THE EXTENSION MODULE

1) Remove the extension connector cover located at the side of the basic module.

2) Connect the extension module.

3) Mount the combined module on a DIN rail.
