Application Blocks For Nodal Functionality - Siemens SIPLUS RIC IEC on S7 Manual

3. Application blocks for nodal functionality

Basically two packages are available for the SIPLUS RIC IEC on S7: Slave and Master function.
Slave (SL) blocks perform the classical substation functions like capture of indication / measured values
or command output.
Master (MA) blocks perform control center tasks like taking over of states in images, initiation of com-
mands etc.
The FB161 and FB166 blocks described here are application blocks performing Master as well as Slave
functions.
For more detailed information about Slave and Master blocks we refer you to the SIPLUS RIC IEC on S7
manual V1.4.
Notice!
All application blocks are designed exclusively for the OB1 priority level. The FB100
communication blocks ('S7_IEC_Config') also have to be operated in priority level OB1!
Note to the CFC plan view
The CFC views included in the manual are used exclusively for explanation purposes. CFC
is not required for using the blocks. The standard programming options in SIMATIC are
sufficient.
