At deployment of a redundant slave, the diagnostic message is expanded
for 8Byte data with the redundancy state. This diagnostic addition is not
stored in the internal diagnostic buffer. The redundancy state has the
following structure:
Redundancy state
Byte Description
X 08h: length of redundancy state permanent at 8
X+1 80h: type of redundancy state
X+2 00h: reserved, permanent 00h
X+3 00h: reserved, permanent 00h
X+4 00h: reserved, permanent 00h
X+5 Red_State slave that communicates with the respective master)
Bit 0 = slave is backup slave
Bit 1 = slave is primary slave
Bit 2 = reserved
Bit 3 = reserved
Bit 4 = slave is in DataExchange
Bit 5 = reserved
Bit 6 = reserved
Bit 7 = reserved
X+6 Red_State of second slave
X+7 00h: reserved, permanent 00h
As from GSD version 1.30 from VIPA, the virtual module "State byte
IM253-2DP50" is available in the hardware catalog. When using this
module during the project engineering. You may define an address range
of 2Byte where the Red_State byte of both slaves shall be stored.
Please regard that you have to configure this module always at the last
slot, otherwise the slave will throw a parameterization error.
Via the parameterization window of the slaves, you may influence the
diagnostic functions by activating res. deactivating diagnostic or the
redundancy state.
