Creating potential groups
6.4 Creating potential groups
Power Feeding modules can be used to create potential groups. The potential isolation of potential
groups to the left of the respective power distribution modules is provided by the base modules.
6.5 Plugging and pulling electronics modules
BL67 enables the pulling and plugging of electronics modules without having to disconnect the field
wiring. The BL67 station remains in operation if an electronics module is pulled.
The voltage and current supplies as well as the protective earth connections are not interrupted
6.6 Extending an existing station
6.7 Firmware download
A firmware download is done via the service interface at the gateway by using the software tool
I/O-ASSISTANT 3 (FDT/DTM) (please find more information in the online help).
Note
Please find any information about the bus-independent, module specific current
consumptions in the manual "BL67- I/O-modules" (TURCK-Documentation No.: German
D300572/ English D300529).
Attention
If the field and system supplies remain connected when electronics modules are plugged or
pulled, short interruptions to the module bus communications can occur in the BL67 station. This
can lead to undefined statuses of individual inputs and outputs of different modules.
Attention
Please note that extensions to the station (mounting further modules) should be carried out only
when the station is in a voltage-free state.
Attention
The station should be disconnected from the fieldbus when downloading.
Firmware must be downloaded by authorized personnel only.
The field level must be isolated.
