Commissioning Insertion of the Function Blocks into the Program Content of the The following blocks are required for the Modbus communication: MODBUS library. MODBUSPN. MODCLI. MODSERV. TCPCOMM The blocks have to be copied from the library into your project. Additionally, the library contains the parameter data block MODBUSPARAM as a draft. Parameterisation of the Modbus Communication Parameterization of the Modbus Communication General For the communication via the integrated PN interface of the PLC, a network Information configuration in NetPro is not necessary.
The connections are established and terminated by means of the function blocks TCON (FB65) und TDISCON (FB66). Modbus parameters) is created. It is recommended to use the wizard for the parameterization of the block MODBUSPARAM. You can find the wizard at MODBUS / TCP communication via the integrated PN interface of the CPU 2XV9450-1MB02; Manual edition 2.1. Parameterisation of the Modbus Communication Editing the Parameterization Procedure Copy DB2 of the library ModbusPNCPU and insert them in your project. If the number is already used, rename the DB.
The parameter of data block MODBUSPARAM must not be changed during runtime. CPU416 The values vary depending on the used firmware. You can find further information on the internet: activeest This parameter defines the way the connection is established (active or passive). It is recommended that the Modbus client performs an active connection establishment while the Modbus server establishes passive connections. Parameterisation of the Modbus Communication localtsapid This parameter defines the local port number. The representation depends on the parameter connectiontype.
The value range depends on the PLC. The port number has to be unique within the PLC. With connectiontype B#16#01 localtsapid1 low byte of the local port number in hexadecimal localtsapid2. Parameterisation of the Modbus Communication Adaption of the The Modbus parameters in the block MODBUSPARAM define the mode of operation of the Modbus communication and the address reference of Modbus Modbus addresses and SIMATIC addresses.
Parameters serverclient TRUE: S7 is server FALSE: S7 is client In operating mode “S7 is client”. Parameterisation of the Modbus Communication connectat This parameter defines the point in time at which the connection is being established. Startup FALSE: establish connection when ENQENR=TRUE TRUE: establish connection immediate after PLC start-up When connectatstartup = TRUE, the first request should be started after the connection was established (CONNESTABLISHED = TRUE) or an error has been reported respectively (ERROR =TRUE).
Parameterisation of the Modbus Communication startx Startx specifies the first register or bit address, which is stored in the data element 0 of the DB. Endx defines the of the last MODBUS address. Endx When accessing registers, the number of the data element of the S7 DB in which the last register is mapped, can be calculated with the following formula: DBW number = (endx –.
Licensing Licensing General The block MODBUSPN must be licensed for each CPU individually. The licensing takes place in two steps: reading the IDENTCODE and declaring the registration key REGKEY. To read the IDENTCODE please proceed as follows: Read the IDENTCODE 1. Copy this string per copy/paste from the DB und and insert it in the form IT4Industry SOFTWARE REGISTRATION FORM. This form is stored in the library path. Program Files Siemens Step7 S7LIBS ModbusPNCPU during installation and is also available on the installation CD. Insert the License-No.
Of the product package into the form. Licensing Declaration of the The registration key REGKEY must be declared for each call of the block MODBUSPN. Registration Key REGKEY The registration key REGKEY should be stored in a global DB.
Via this global DB all MODBUSPN blocks can receive the registration key (See also the following example). Licensing Missing or Wrong When the registration key is missing or a wrong one is detected, the SF LED (S7-300 and IM151-8) or the INTF LED (S7-400) of the CPU is flashing.
A Licensing cyclic error message regarding the missing license is displayed in the diagnostic buffer too. Function Block MODBUSPN Function Block MODBUSPN Functionality of the FB General The function block MODBUSPN enables a communication between a PLC with integrated PN interface and a partner which supports Open Information MODBUS/TCP. The function codes 1, 2, 3, 4, 5, 6, 15 and 16 are supported. Depending on the parameterization, the FB can be operated either in client or in server mode.
Function Block MODBUSPN Call of the FB For a correct program sequence the function block MODBUSPN has to be called in 3 organization blocks:. OB100 Start-Up. OB121 Programming Error.
Cyclic OB (OB1 or cyclic interrupt OB, e.g. OB35) The subordinate blocks of the Modbus library MODCLI, MODSERV and TCPCOMM must not be called additionally in an organization block. Function Block MODBUSPN Connection Active connection establishment can be carried out by the Modbus client as well as the Modbus server.

It is recommended explicitly that the Modbus client Handling executes the active establishment. The relevant information is read from the connection parameters of DB MODBUSPARAM.
Function Block MODBUSPN Initiate Request A rising edge at the trigger input ENQENR initiates a request. Depending on the input parameters UNIT, DATATYPE, STARTADDRESS, LENGTH, TI S7 is Client and WRITEREAD, a MODBUS request telegram is generated and sent to the partner station via the TCP/IP connection. Function Block MODBUSPN Parameters of the Function Block MODBUSPN Parameter Decl. Type Description Value range Init WORD Connection ID, must be identical to the 1 to 4095 associated parameter in the local W#16#1 to connection description W#16#FFF DBPARAM BLOCK Number of the parameter DB depending on RECVTIME TIME. Function Block MODBUSPN Parameter Decl. Type Description Value range Init ERROR OUT BOOL An error has occurred TRUE No error has occurred FALSE STATUS OUT WORD Error number for protocol errors when 0 to FFFF MODBUS evaluating a Modbus telegram STATUS OUT WORD Error number for connection errors during.
Function Block MODBUSPN General The parameters of the FB MODBUSPN can be divided into two groups: Information. Initialization parameters. Runtime parameters Initialization parameters are evaluated only during the call of OB100 and are adopted into the instance DB. They are marked with “yes“ in the column “INIT“. Function Block MODBUSPN To each connection between the PN PLC and a communication partner a connection ID is assigned. When operating various connections an individual ID is required for each logical connection.
This connection ID is defined in the connection parameter block, which is part of the parameter data block MODBUSPARAM. Function Block MODBUSPN ENQENR Operating mode S7 is Client: The data transfer is initiated with a TRUE edge at the input. The request telegram is generated with the values of the input parameters UNIT, DATATYPE, STARTADDRESS, LENGTH, TI and WRITEREAD. A new request may only be initiated when the previous one is ended with DONENDR or ERROR.
Function Block MODBUSPN DONENDR The parameter DONENDR indicates an error-free execution of the request. In the operating mode S7 is Client, the activated request was executed without an error.
With a reading function, the response data from the server has already been entered into the DB. With a writing function, the response to the request telegram has been received from the server. Function Block MODBUSPN DATATYPE The parameter DATATYPE defines which Modbus data type is to be accessed with the current job.
The following data types are available: Coils B#16#1 Inputs B#16#2 Holding Register B#16#3 Input Register B#16#4 In the operating mode S7 is Client, DATATYPE is an input parameter. In the operating mode S7 is Server, DATATYPE is an output parameter.
Function Block MODBUSPN The parameter TI (Transaction Identifier) is copied by the server from the request telegram to the respond telegram according to the MODBUS specification. In the operating mode S7 is Client, this is an input parameter. The FB copies this value to the request telegram and verifies it when receiving the respond telegram.
