Introduction The products described in this manual should be installed, operated and maintained only by qualified application programmers and software engineers who are almost familiar with EN 61131-3 concepts of PLC programming, automation safety topics and applicable national standards. Using this manual Specifications within the text of this manual are given in the International System of Units (SI), with non SI equivalents in parentheses.
sigmadue - IEC 61131-3 Function Block Library Purpose The purpose of this document is to describe the structure and use of Ascon Spa’s proprietary IEC61131-3 libraries. These libraries cover different aspects of the features of the CU-02 and MP-01 units: from I/O modules interface to Modbus access from the control to the logic management. Caution The function blocks of the various libraries are valid for both CU-02 and MP-01 units except when it is expressly indicated.
Chapter 1 AsconACLib 1-1 Purpose The purpose of this document is to provide a complete description of the library AsconACLib. 1-2 Descritpion The AsconACLib is a function block library that contains a set of generic functionalities that come from the Ascon AC Station Device useful for the IEC 61131 programming. The table here reported gives the complete list of the function blocks of the library.

Chapter 5 AsconMBCommLib 5-1 Purpose The purpose of this document is to supply a complete description of AsconMBCommLib Library project. 5-2 Description AsconMBCommLib is a Function Block library which simplifies the access to the MODBUS communication ports available in Ascon SpA sigmadue line devices. The following is the list of FBs present in the library.

Chapter 5 - AsconMBCommLib 5-2-1 Communication port configuration The SERIAL_PORTS/MP_SERIAL_PORT and TCP_IP_PORT FBs enable the communication port configuration. The communication parameters (baudrate, logic ports), the desired protocol type (MODBUS SLAVE, MODBUS MASTER), the desired communication port (RS232, RS485 or Ethernet connection) can be thus assigned. The figure below shows an example of port communication configuration.
sigmadue - IEC 61131-3 Function Block Library 5-2-2 Modbus Slave Protocol Once the communication port has been configured as slave (or server in case of MODBUS/TCP), the data exchange between the program written in the IEC61131 environment and the memory area, that can be seen from the master (or client in case of MODBUS/TCP), can occur in two different ways: • by declaring and using the %M variables; • by using the Function Blocks in AsconMBCommLib library.

sigmadue - IEC 61131-3 Function Block Library 5-2-3 Modbus Master protocol The sigmadue CPU device firmware includes the communications primitives for MODBUS MASTER RTU (see “Serial Communication Function Block Library”). The definition of Function Blocks simplifies its use and enables to define the sequence of messages to be generated by the MODBUS master, after correctly configurating the communications port. The following example shows how to use the library master Function Blocks1.
