Figure 4-13: Example - remote acknowledgement
Configure the "Ext. acknowledge"
LogicsManager
function as above using the and as well as the softkey
and confirm the change by pressing the softkey:
With this setting, the "Ext. acknowledge"
LogicsManager
output becomes TRUE as soon as the remote acknowl-
edge signal is enabled.
NOTE
The
LogicsManager
commands 2 and 3 may be used to configure additional conditions like discrete
inputs, which must be energized to be able to issue the remote acknowledge command.
Please refer to the Interface Manual 37430 for a description of how to configure the
LogicsManager
functions via
Modbus.
NOTE
All interfaces access to the same bits. The command variable "04.13 Remote request" remains enabled
in the easYgen until a new command is sent or the power supply failed or is removed.
Remote start:
The command variable "04.13 Remote request" changes to "1" (high) if the start bit (ID 503, bit 0)
changes from "0" to "1". The command variable "04.13 Remote request" changes to "0" (low) if the stop bit
(ID 503, bit 1) changes from "0" to "1" (refer to Figure 4-14 on page 26).
Acknowledgement:
The command variable "04.14 Remote acknowledge" reflects the acknowledgement bit
(ID 503, bit 4).
An acknowledgement is generally performed twice:
•
1
st
change of the logical output "External acknowledge" from "0" to "1": Silence horn
•
2
nd
change of the logical output "External acknowledge" from "0" to "1": Acknowledges all inactive alarms
ATTENTION
The easYgen does NOT react on the disabling of the start bit, but only on the enabling of the stop bit.
This has the advantage that it is not required to maintain the connection established for the whole time
in case of a remote start.
