Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by personnel qualified for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and

Preface
Purpose of the documentation
This device manual complements the system manual S7 1500 Automation System
(http://support.automation.siemens.com/WW/view/en/59191792). General functions of the
S7-1500 are described in the S7-1500 Automation System System Manual.
Conventions
This documentation contains figures of the described device. The figures may differ slightly
from the devices supplied.
Please also observe notes marked as follows:
Note
A note contain important information on the product described in the documentation, on the
handling of the product and on the section of the documentation to which particular attention
should be paid.
Note on IT security
Siemens offers IT security mechanisms for its automation and drive product portfolio in order
to support the safe operation of the plant/machine. We recommend that you inform yourself
regularly on the IT security developments regarding your products. You can find information
on this on the Internet (http://support.automation.siemens.com).
You can register for a product-specific newsletter here.
For the safe operation of a plant/machine, however, it is also necessary to integrate the
automation components into an overall IT security concept for the entire plant/machine,
which corresponds to the state-of-the-art IT technology. You can find information on this on
the Internet (http://www.siemens.com/industrialsecurity).
Products used from other manufacturers should also be taken into account here.

Connecting cables
Standard connecting cables of various lengths (see chapter Accessories (Page 11)) are
available for connection with a communication partner which also has a 9-pin sub-D male
connector.
Please note that you must only use shielded connector casings and cables. A large surface
area of the cable shield must be in contact with the connector casing on both sides.
NOTICE
Never connect the cable shield with the GND, as this could destroy the interfaces. GND
must always be connected on both sides (pin 5), otherwise the modules could be
destroyed.

To take into consideration
The general installation guidelines must be taken into consideration (see function manual
EMC/EMI compatible installation of control systems
(http://support.automation.siemens.com/WW/view/en/59193566)).
The cable shield must be installed on a grounding rail to maintain the EMC values
(electromagnetic compatibility).

Parameter assignment
Introduction
You configure and assign the parameters of the communication module with STEP 7
(TIA Portal V12 or later) or with STEP 7 with integration of a GSD file.
Additional information
The device manual of the communication module is supplemented by the function manual
CM PtP - Configurations for point-to-point connections
(http://support.automation.siemens.com/WW/view/en/59057093) and the TIA Portal
information system.
There you will find information on the following topics:
● Operating modes
● Receive buffer
● Data flow control
● Transmission integrity
● Data transmission - protocol specific
● Programming/configuring in STEP 7 (TIA Portal)
● Module-specific instructions
● Diagnostics
4.2
Reaction to CPU STOP
Ongoing transmissions are aborted when the higher-level control (CPU) goes to STOP.
Frames in the receive buffer are retained. With a corresponding configuration in the
properties dialog of the communication module, you can automatically clear the receive
buffer on the communication module during CPU startup.

4.3
Address space
Address space of the communication module
The input addresses of the communications module total 8 bytes. The input addresses are
automatically assigned for each communications module when you specify the device
configuration in STEP 7 (TIA Portal). Output addresses are not required.
Hardware identification (not freely configurable)
The hardware identification (HW ID) is automatically assigned for each communications
module when you specify the device configuration in STEP 7 (TIA Portal).
The hardware ID is issued along with the diagnostic messages to localize the module. In
addition, the HW identification is required for S7-1500 at the communication instructions in
order to identify the communication module. For S7-300/400, the communication module is
identified by the start address of the input data.

Programming
Overview of the instructions
Communication between the CPU, the communication module and a communication partner
takes place by means of special instructions and protocols that support the corresponding
communication modules. The instructions process the exchange of data between the CPU
and the communication module. They must be called cyclically from the user program. Data
transmission takes place asynchronously across several cycles.
The transmission protocols are implemented on the communication module. The protocol is
used to adapt the interface of the communication module to the interface of the
communication partner.

parameters.
Send_Config
You use the Send_Config (send configuration) instruction to dynamically
assign serial send parameters of a port.

Receive_P2P
You use the Receive_P2P instruction to receive data from a communication
partner.
Receive_Reset
You use the Receive_Reset instruction to delete the receive buffer of the
communication module.
Signal_Get
You use the Signal_Get instruction to read the RS232 accompanying
signals.
Signal_Set
You use the Signal_Set instruction to set the RS232 accompanying signals.
Get_Features
You use the Get_Features instruction to read expanded functions supported
by the communication module.
Set_Features
You use the Set_Features instruction to set expanded functions supported
by the communication module.
USS_Port_Scan
You use the USS_Port_Scan instruction to communicate via the USS
network.
USS_Drive_Control
You use the USS_Drive_Control instruction to exchange data with a drive.
USS_Read_Param
You use the USS_Read_Param instruction to read parameters from the
drive.
USS_Write_Param
You use the USS_Write_Param instruction to change parameters in the
drive.
Modbus_Comm_Load
The instruction Modbus_Comm_Load allows you to configure the port of the
communication module for Modbus RTU.

Instruction
Meaning
Modbus_Master
The instruction Modbus_Master allows you to communicate as Modbus
master by means of the PtP port.
Modbus_Slave
The instruction Modbus_Slave allows you to communicate as Modbus slave
by means of the PtP port.
The instructions are part of STEP 7 (TIA Portal). The instructions are available in the "Instructions"
task card under Communication > Communication processor.
