4.2.2.2 Connecting the equipotential bonding circuit

Potential differences

Differences in potential between spatially separated system parts can lead to high equalizing
currents over the data cables and therefore to the destruction of their interfaces. This
situation may arise if the cable shielding is terminated at both ends and grounded at different
system parts.

Potential differences may develop when a system is connected to different mains.

General requirements of equipotential bonding

Potential differences must be reduced by means of equipotential bonding in order to ensure
trouble-free operation of the relevant components of the electronic system. The following
must therefore be observed when installing the equipotential bonding circuit:

● The effectiveness of equipotential bonding increases as the impedance of the
equipotential bonding conductor decreases or as its cross-section increases.

● If two system parts are connected to each other via shielded data lines with shielding
connected to the grounding/protective conductor on both sides, the impedance of the
additionally installed equipotential bonding cables may not exceed 10% of the shielding
impedance.

● The cross-section of a selected equipotential bonding conductor must be capable of
handling the maximum equalizing current. The best results for equipotential bonding

2

between two cabinets were achieved with a minimum conductor cross-section of 16 mm

.

● Use equipotential bonding conductors made of copper or galvanized steel. Establish a
large-surface contact between the equipotential bonding conductors and the
grounding/protective conductor and protect these from corrosion.

● Terminate the shielding of the data cable on the HMI device flush and near the
equipotential busbar using suitable cable clamps.

● Route the equipotential bonding conductor and data cables in parallel with minimum
clearance between these. See the wiring diagram.

NOTICE

Equipotential bonding conductor
Cable shielding is not suitable for equipotential bonding. Always use the prescribed

equipotential bonding conductors. The minimum cross-section of a conductor used for
equipotential bonding is 16 mm². When you install MPI and PROFIBUS DP networks,
always use cables with a sufficient crosssection since otherwise the interface modules

may be damaged or destroyed.

Introduction

This section is intended for configuration engineers of the HMI device.
The following chapter contains information necessary for configuring:

● Connection options to the PLC

● Communication using WinCC flexible

4.4.1 Topologies

Introduction

The HMI device and PLC can communicate using a PtP connection or within a network.
The HMI device can communicate only with one S7-200 at a time.

4.4.1.1 Communication via a point-to-point connection

In a PtP connection, the HMI device is the only device which is connected directly with the
S7-200. You need an MPI cable or a PROFIBUS bus cable with two PROFIBUS bus
connection plugs to connect the HMI device to the PLC.

4.4.1.2 Communication in the network

Introduction

A network consists of several nodes which are connected to the same bus cable and
communicate with each other. All nodes are assigned a unique network address. Which
devices communicate with each other is defined when the devices are configured.

A network must contain a master station and active nodes and may contain slave stations
and passive nodes. The master actively transmits requests to other devices and can also
respond to requests from other masters. A slave only responds to requests.

You need a PROFIBUS bus cable with PROFIBUS bus connector to install a network.
The HMI device always operates as master station.
The HMI device can communicate only with one S7-200 within the network.

S7-200 as active or passive node

The S7-200 station may be operated on the network in master mode (PPI/master mode) and
in slave mode (PPI/slave mode). The default setting of the S7-200 station is PPI/slave mode.

The OP 73micro and TP 177micro can communicate with a SIMATIC S7-200 in PPI/slave
mode and with a SIMATIC S7-200 in PPI/master mode. The HMI device can be connected
via the CPU interface of the SIMATIC S7-200.

4.4.1.3 Configuration instructions

Please observe the following configuration instructions:

Note
For a first-generation SIMATIC S7-200 (CPU 214, 215, 216), use the connection at Port 1 for

communication via MPI/PROFIBUS DP. When using a CPU 214, set a baud rate of

9.6 Kbps.

Note
A cable must be terminated with its characteristic wave impedance. To do this, enable the

terminating resistor on the first and last node of the PROFIBUS/MPI network.
Both nodes must be supplied with power. Of the first and last end nodes of a

PROFIBUS/MPI network, only one can be an HMI device! No other HMI devices should be
connected to the network as terminal nodes.

The RS485 PROFIBUS terminal and the PROFIBUS connector are equipped with a switch
for setting the terminating resistor. Meaning of the ON and OFF switch settings:

OFF: The terminating resistor is disabled, i.e. the bus segment is not terminated.
ON: The terminating resistor is enabled, i.e. the bus segment is terminated.

4.4.2 Configuring communication

Requirements

The following software components are required for communication:

● WinCC flexible configuration software

● STEP 7 MicroWIN configuration software for the SIMATIC S7-200 controller

4.4.3.1 Communication between HMI device and controller

Communication principle

The HMI device and the S7–200 controller communicate using

● tags and

● user data areas

Tags

The controller and the HMI device exchange data using process values. During
configuration, tags are created pointing to addresses in the PLC. The HMI device reads the
value from the specified address and displays it. The operator can also make an input on the
HMI device that is then written to the address on the controller.

user data areas

In the case of the OP 73micro and TP 177micro, the user data area serves for transmitting
the date and time from the PLC to the HMI device.

User data areas are set up when you create the project in the project window in
WinCC flexible of the HMI device by selecting "Communication ▶ Connections" in the "Area
pointers" work area. Physically, the user data area is in the PLC.

4.4.3.3 Time synchronization via area pointer

Introduction

When the "Date/Time PLC" area pointer is configured, the HMI device reads the date and
time cyclically from the PLC. The position of the "Date/Time PLC" user data area is defined
in the area pointer.

Procedure

To configure the address of the area pointer, select "Communication ▶ Connection", then
select "Area pointer."

● Length
The default length of the area pointer is set by WinCC flexible.

● Acquisition cycle
Here, define an acquisition cycle to enable the HMI device to read an area pointer

cyclically. Make allowances for the fact that a shorter acquisition time may have a
negative influence on HMI device performance.

● Comment

This is where you can save a comment which describes the use of the area pointer, for
example.

Function

The PLC describes the data area of the "Date/Time PLC" area pointer. All specifications are
coded in BCD format.

The HMI device reads the data cyclically based on the configured acquisition cycle and
synchronizes itself.

Note
Do not configure an extremely short acquisition cycle for the date/time area pointer because

this will have a negative influence on HMI device performance.
Recommendation: Acquisition cycle of 1 minute, if the process allows this.

The HMI device time has a resolution of seconds, regardless of the acquisition cycle.

The date/time data area has the following structure:

DATE_AND_TIME format (in BCD code)

7 . . . . . . 0 7 . . . . . . 0

n+0 Year (80-99/0-29) Month (1-12)

4.4.3.4 Mechanism of error alarm acknowledgment

Introduction

Alarms indicate the process and plant states on the HMI device.
Alarms are configured in WinCC flexible. Each alarm is assigned an alarm bit in the PLC.

Each alarm bit must be a tag or tag element which is configured in WinCC flexible.
Various alarm classes are available. Alarms of the "Error" class must be acknowledged

because of their importance.
The following distinctions are made for acknowledgments:

● Acknowledgment on the HMI device

● Acknowledgment by the PLC

Acknowledgment by the PLC

Acknowledgment of error alarms by the PLC requires the "Write acknowledgment tag"
function to be configured.

When "Write acknowledgment tag" is set in the PLC, the system automatically acknowledges
the corresponding error alarm. This function is identical to the acknowledgment function on
the HMI device, for example, triggered with the "ACK" button.

The "Write acknowledgment tag" bit and the alarm bit must be set in the tag.
Reset the acknowledgment bit before the alarm bit is set again in the error alarm area. The

figure below shows the pulse diagram.

Acknowledgment on the HMI device

The PLC can only detect an error alarm acknowledgment at the HMI device if the "Read
acknowledgment tag" bit is configured. The HMI device sets the "Read acknowledgment tag"
bit in the PLC after it has acknowledged an alarm.

In order to generate a signal transition each time the acknowledgment bit is set, the HMI
device initially resets the corresponding "Read acknowledgment tag" bit when an error alarm
bit is set. There is a certain time-based offset between these two operations due to the
processing time of the HMI device.

The figure below shows the pulse diagram.

7.1 Overview

Configuration and process management phases

HMI devices can be used to operate and monitor tasks in process and production
automation. The plant screens on the HMI devices are used to provide a clearer overview of
active processes. The HMI device project, which includes the plant screens, is created
during the configuration phase.

Once the project is transferred to the HMI device and the HMI device is connected to a PLC
in the automation system, processes can be operated and monitored in the process
management phase.
