Input Words

Purpose

This section describes input words.

Input Words 3x ... 3x + 15

16 words of input data are used for 6 120VAC input points and the Modbus master response buffer.

Input Words Control Mode 1

Input Words Control Modes 2 ... 8

Input Word 1

Input word 1 contains an echo of the sequence number.

Valid settings are 1 ... FFFF
Whenever the module is set to zero, it goes to the module shut down state.
When the value in the first input word is not equal to the output word then a Modbus message will be sent. If not, when they are equal, there will be no message activity.
A change in the sequence word value starts the Modbus command execution. It is your responsibility to change the output data for the Modbus message. The sequence number must be the last word of information written in order to ensure Modbus messages are correctly handled.

Input Word 2

Input word 2 contains 6 bits of 120 VAC input data and 8 bits for module status.

Input Word 1 High Byte (Status).

Bit 15 (MSB)	0= message processing done 1= message in process
Bit 14	Copy of output 3
Bit 13	Copy of output 2
Bit 12	Copy of output 1
Bit 11	Not used
Bit 9	1= fuse ok 0= fuse blown
Bit 8	1= module healthy 0= module not healthy
