Huawei ECC800-Pro - Linkage Control Configuration Examples

– Register: A register can combine multiple levels of logic programs.
– Alarm: The operation result is generated as a new alarm.
Feature Description
The linkage control conguration is concise and easy to operate. You can perform
the following operations:
●
Congure linkage control logic programs on the WebUI for display.
● Import or export
conguration les.
● Restore the default linkage control conguration by one click.
The following are descriptions of the WebUI:
● Basic Parameters: The congurations of the linkage control logic programs
are valid if Enable linkage control function is set to Yes.
● Linkage group: You can
congure Linkage groups by type.
● Linkage Logical List: You can
congure logic program lines.
● Import and Export: You can import or export
conguration les to generate
logic program lines in batches.
● Restore conguration: You can click Restore Factory Defaults to restore the
default linkage control congurations.
9.2 Linkage Control Conguration Examples
Context
NO TICE
● Linkage control does not need to be congured onsite and its default
conguration applies. Before adding or modifying linkage control linkage logic,
consult Huawei engineers.
● When you do not know how to rectify the incorrect linkage control
conguration or want to synchronize the linkage control conguration from
another ECC800-Pro, use the linkage control
conguration import and export
function.
● The ECC800-Pro supports re control linkage and high temperature linkage
control. For example, the ECC800-Pro can implement re linkage by detecting
re alarms through the re controller and opening the skylight, opening the
aisle door, and shutting down the smart cooling product based on the alarm
status.
● The following describes how to congure the linkage control linkage, using
Link
re control with skylight open as an example.
● In this example, the re controller connects to port AI/DI_1. The actual port
prevails.
