■ STATUS

Analog input modules without extension module (models: R7C-SV4, R7C-TS4, R7C-RS4, R7C-RT4A, R7C-MS4, R7C-CT4E)

can show input status of each channel. Analog output modules (models: R7C-YV2, R7C-YV4, R7C-YS2, R7C-YS4), discrete I/O

modules (models: R7C-DA16, R7C-DCx, R7C-RR4) and Totalized pulse input module (R7C-PA8) show '0' at the same address.

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.

■ OUTPUT AT THE LOSS OF COMMUNICATION

• For the extension module R7C-DA16, R7C-DC16x or R7C-DC8E

The extension modules (R7C-EC8A, R7C-EC16A, R7C-EC8B, R7C-EC16B, R7C-EC8C) are set to ‘Reset Output’ or ‘Hold Output’

according to the setting of SW1-5 of the module.

• For the extension module other than R7C-DA16, R7C-DC16x or R7C-DC8E

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