  1. Hello, I'm have some problems with the conversion of two integers to a floating point value. I have a modbus energy meter (SDM120) who works with 32bit IEEE745 floats values. In visilogic I receive two 16bit integers (MI); MI0 : 15643 MI1: -23069 I converted these integers to bits by the 'num to bit' function block. These are the converted value's : MI0 : 15643 --> 0011 1101 0001 1011 MI1: -23069 --> 1010 0101 1110 0011 If I put the two value's behind eachother I get the following binary code: 0011 1101 0001 1011 1010 010
  2. Hello, For a project im working on I need to motitor serval energy sources and control multiple relays. I would like to use the Samba 4.3" PLC for giving a nice interface to the system. The problem is that I have over 30 outpust I need to control. I've found a modbus RTU (RS485) energy meter who measures the voltage and current. Also found a modbus RTU (RS485) digital output module with 16 outputs. Is it possible to use the Samba 4.3" PLC with V100-17-RS4 module to communicate over modbus with the IO modules and energy meters? Best Regards, Jelmer
