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
Hi, Would someone explain me how can I send correctly variables type REAL (MF`s) over Modbus-TCP? I am working with a PLC V1210 with Internet card V200-19-ET2, it talks to an Anybus X-gateway ( AB7629-F) which is Profibus-Master and Modbus Slave then the Anybus will send the data to a Nachi Robot CFD controller. I already set the comms between all devices and I can send/receive data to each other. My problem starts when I try to send the variable with decimal point (i.e 1.5) to the robot. But let me explain where I have got so far. Before send it to the robot I get the MF0 and
Hi, May be this is an old topic. I have done my project in 9.3.0 before. For MF values give the min and max values through the HMI tab itself and that doesn't show any compilation errors. After I download and use 9.4.0 I couldn't set the value which causes so many compilation errors. How could I rectify that. (removing all set values and do it by means of ladder...?).
