Internal Module
Registers
The TSX ETG 1000 module provides four register zones:
l User zone,
l Command zone
l Diagnostic zone
l Periodic zone
The user zone (registers 0 to 63).
This zone is available for unrestricted use. The user can read or write in this zone
by means of Modbus TCP requests or by RDE/GDE (data table/graphics objects).
This zone can be used in various ways:
l to send a mail from an Ethernet network
l to send a mail without a Modbus device: test email
l to store device values or to exchange values between devices
l to simulate a Modbus device,
l etc.
The command zone (register 500 to 511):
