Modbus Tango C++ class MODBUS RTU/TCP protocol implementation • The class has been recently refurbished (28/01/2016) • Usage of non blocking TCP socket for a best management of timeout and reconnection • Best handling of errors • Modbus. Core. SL. cpp file has been removed • Tango interface and configuration 100% compatible 28/11/2020 Jean-Luc PONS, 30 th tango meeting 2

Modbus. Composer Tango C++ class Create dynamic attributes and commands above a MODBUS device • Dynamic attributes – Expressions are parsed once and evaluation trees are used for calculation – Expressions can use other attributes (internal or external) – Management of unsigned type – Support for spectrum attributes – Full description of supported grammar for expression can be found here: http: //www. esrf. eu/computing/cs/tango_doc/ds_doc/tango-ds/Calculation/Modbus.

Modbus. Composer Tango C++ class • Dynamic commands Dynamic_commands device property – Only VOID command Reset=Write. Int(0 x 3029, reg(0 x 3029)|0 x 0100) On=Write. Int(0 x 3029, reg(0 x 3029)|0 x 0010) Off=Write. Int(0 x 3029, reg(0 x 3029)&~0 x 0010) 28/11/2020 Jean-Luc PONS, 30 th tango meeting 5

Modbus. Composer Tango C++ class • State management Dynamic_states device property FAULT = not flag(0 x 3031, 7), Depression air flow ALARM = Water. Flow<213, Flow too low ALARM = Water. Out. Temp>23. 4, Temp too high ON = flag(0 x 3031, 13), Device is ON OFF = 1, Device is OFF Highest precedence Lowest precedence • Modbus_name device property Name of the Modbus device 28/11/2020 Jean-Luc PONS, 30 th tango meeting 6

Logix 5000 Tango Java class CIP Ether. Net/IP protocol implementation • C. I. P. Common Industrial Protocol • Support only C. I. P. over TCP/IP (Ether. Net/IP) • Map ‘tagged’ variables coming from the PLC to tango attributes • Supports only BOOL, SINT, DINT, REAL CIP data type • Supports scalar and spectrum • Tagged variables writing not fully tested 28/11/2020 Jean-Luc PONS, 30 th tango meeting 7
