Switch to Remote Control or back to Manual Control
Before you can control a unit from remote, it is required to switch it to remote control. This
is done by sending a certain command.
Notes:
A 6RL unit will never switch to remote control automatically and cannot be remote
controlled while in this condition. Reading status and values is always possible.
The unit will never exit remote control automatically, unless it is switched off or the
mains supply is otherwise interrupted. Remote control can be exited by a certain
command. It then switches back to manual control.
Switching to remote control may be inhibited by several circumstances and is usually
indicated by an error message:
Condition “Local“ is active (check the display on the front of your unit or read the
device status), which will prevent any remote control
The unit is already remotely controlled by another interface
The unit is in setup mode, means the user has accessed the setup menu and not left
it yet.
How to Switch a Unit to Remote Control:
1)
If you are using the ModBus RTU protocol, you need to create and send a message
according to the description above, for example 00 05 01 92 FF 00 2D FA
2)
Once the switchover to remote control has been successful, the unit will usually indicate
the new condition in the display, as well as it echoes the message as a confirmation
In case switching to remote control would be denied by the unit, because option “Allow
remote control = No” is set, then the unit will return an error message like 00 85 17 53 5E.
According to ModBus specification, this is error 0x85 with error code 0x17.
Leaving remote control can be done in two ways, one of which is using the dedicated
command or by switching the unit to “Local” condition.
How to Exit Remote Control:
If you are using the ModBus RTU protocol, you need to build and send a message according
to the description above, for example 00 05 01 92 00 00 6C 0A.
