INFORMATION
Throughout this document, when reference is made to any
registers, the notation of registers and their addresses follows
a consistent format:
▪
H0010
where
H
indicates a holding register, and
0010
refers to the register address.
▪
I0010
where
I
indicates an input register, and
0010
refers
to the register address.
6.3.3 Modbus master timeout
The EKMBPP1 can be configured to operate with an optional Modbus
master timeout. When no holding register occurs for a period of
120 seconds, a timeout event occurs: all units switch on with their
current settings and the status LEDs indicate an RS485 communication
timeout. For more information about LED behaviour, see
"6.1 Status
LEDs" [
