Miscellaneous Commands and Topics MODBUS CANBUS FONTS COLOURS FORMAT DATA ARRAYS INLINE FUNCTIONS ERROR CODES Update information is provided at the end of each section Communication protocols and data storage are a key requirement of any HMI solution. MODBUS is a popular protocol for process control and actively works with register arrays. We provide master and slave processing for MODBUS, CANBUS and other USER defined protocols which can be created within the receive and transmit routines. Error codes provide a traceable value for reporting functional problems during communication and operation. Data formatting allows conversion to match application requirements, while a comprehensive set of fonts and colours enables optimum readability and layout. Inline functions allow short functional code to be embedded into KEYS and IF actions.
