an additional protocol option for use with the uLynx Ethernet coprocessor.
Other Tabs
Timer Settings
The timer settings control how long the RTU will wait to energize or de-energize a relay output when it has been told to come
on or go o. These timers will always be used regardless of the mode of operation - Micro-Comm CTU control, Script Lan-
guage, Modbus or DF1.
Stop/Start Setpoints 1-32
These setpoints can be labeled and accessed from the Micro-Comm Display module and then used in script for control.
Stop and Start setpoints are scaled using the analog selected in the Stop/Start Labels screen.
Use 8-bit Remote Setpoints
This option will force the remote setpoint protocol (used by SCADAview) to use 8-bit (LSB) values. This may be required if the
central is a C2000 or earlier.
Misc.
Pulse Dividers
These sets the number of pulses that must occur before the pulse input counter is incremented.
Normally this will be set to 1.
Expanded Data Station
When this is checked, the primary address will respond with local expanded data when using CTU32 protocol.
