Note!
The following section only applies to devices with LON interface and CO7 -> Fb00 = ON.
On connecting LONMARK devices, CO7 -> Fb00 = OFF needs to be configured.
Each controller is assigned a LON station address, which needs to be set in the PA7 parameter
level. A station address in a subnet must be unique. Each controller type is assigned its own
subnet. This means that identical LON station addresses can be assigned for different controller
types, e.g. 5174 and 5179, as they belong to different subnets. A maximum of 59 participants
consisting of TROVIS 5171, 5174, 5177 and 5179 can be connected together.
Controller type Subnet Station address
TROVIS 5171 1 1 to 20
TROVIS 5174 4 1 to 20
TROVIS 5177 7 1 to 20
TROVIS 5179 9 1 to 20
The controller sends its inputs and outputs as well as pulse counters and their pulse duration
over the LON network to a TROVIS 5171 Programmable Logic Controller.
The pulse inputs are sent after four minutes; the sensor temperatures when the temperature has
changed by at least 1 °C or after four minutes at the latest. The analog inputs and outputs are
sent when the signal level changes by 0.5 V. The binary inputs and outputs are sent after every
change or after four minutes at the latest.
In the InF7 level, all other TROVIS 5100 network participants are listed together with controller
type and LON address (e.g. “74-01“). A communication fault exists when the display blinks.
