Correct usage of Siemens products
Please observe the following:
Electrostatic Sensitive Devices ESD
Definition of ESD Almost all SIMATIC / FUM modules are equipped with highly integrated components or
elements in MOS technology. For technological reasons, these electronic components are very sensitive
to overvoltage and, consequently, to electrostatic discharge:
The short designation for such electrostatic sensitive components/modules is: "ESD", which is the commonly used international abbreviation of ”ESD” (Electrostatic Sensitive Device).
These modules can be destroyed by voltage and energy far below the limits of human perception. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged.

1. General
This manual describes the functionality of the AddOn function blocks FB161 and FB166. They allow the
low effort realization of an IEC nod with the software SIPLUS RIC Application IEC on S7 V1.5.
The present description has to be perceived as a supplement of the SIPLUS RIC IEC on S7 manual V1.5.
You’ll receive the blocks in the form of a SIMATIC block library.
2. Overview Nodal function
The nodal function is a configuration with a SIPLUS RIC IEC on S7 station connected between two IEC
telecontrol equipments for enabling the transmission of information via the telecontrol protocols IEC101
resp. IEC104.
Depending on the case of operation classical control center / substation interlinkings as well as interconnections between several substations can be carried out.
In practice the classical control center / substation link with exchange of information between one or several subordinated RTUs and one control center will be the most used application. Therefore the instructions and figures in the subsequent description apply to this configuration.
In this case SIPLUS RIC IEC on S7 has IEC-Slave function compared to the control center and IECMaster function compared to the subordinated RTU.
The nodal blocks support the easy and extensively non parameterized projection of the information to be
transferred.
The following blocks are available:
FB161 for the control direction
subordinated RTU SIPLUS RIC IEC on S7 Control center
FB166 for the monitoring direction
Control center SIPLUS RIC IEC on S7 subordinated RTU
In control direction the blocks are designed for realization of a “transparent” node:
- for direct passing of information (exception: time stamp, ASDU address conversion).
- automatically update of the image (created during operation)
- In order to transmit measured values not with each change of a bit a global programmable
threshold for slowdown of the measurands was added.
as well as user configurable by assigning of a parameter data block. This implicates the essential features:
- defining the information which has to be transferred (defined quantity structure)
- individual conversion of the information object addresses
- parameterizable threshold for measured values per information
- possibility for image access (diagnosis / further processing)
Interrogation and disturbances are processed out of the image.

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.
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!
Pre-condition for using the nodal blocks is the existence of minimum two IEC-channels in the system.
They mostly consist of an IEC-Slave (as interface to the control center) and an IEC-Master (interface to
the subordinated RTU).
Figure Nodal blocks:
The figure shows the „classical“ information flow from an subordinated station via the node to the control
center (monitoring direction, _MD) resp. from the control center via the node to the subordinated station
(command direction _CD).
Each of the node application blocks (,MaoSLi_MD and ,SloMAi_CD’) have one interface each to the
source and to the target application available, which have to be interconnected according to the following
description
MAoSLi_MD, for the monitoring direction
The flow direction of the information is:
Master (source) -> node -> Slave (target)
The application block , MAoSLi_MD’ is connected via the pointer ‚P_Application (Master)’ with the
‚S7_IEC_Config’ of the Master protocol version (information source) like the MAo-blocks. i.e. the func-
tional block will be linked directly to the IEC-Master-activation.
The link to the Slave-application (information target) is carried out like the activation of the SLi-blocks with
the pointer ‚P_SLi (Slave)’ via an organization block ‚SL_Org_Asdu_1’. The parameterized ASDUaddress from the ‚SL_Org_Asdu_1’ will be also used for the information of the nodal block.
SLoMAi_CD, for the command direction
The flow direction of the information is:
Slave (source) -> node -> Master (target)
The application block ,SLoMAi_CD’ is connected via the pointer ‚P_Application (Slave)’ with the
‚S7_IEC_Config’ of the Slave protocol version (information source) like the SLo-blocks.
The link to the Master-application (information target) is carried out with the pointer ‚P_Application (Mas-
ter)’ to the ‚S7_IEC_Config’ of the Master protocol version like the MAi-blocks.
