DINT to REAL is easy; just about any math instruction will handle that. 20122023, manualsdir.comAll rights reserved. MCM.DATA.ReadData[x] is a (16-bit) INTEGER data type. On the other hand, DINTs are 32 bit tags. Then MSG the Int registers to the PLC5. ElectronGuru - I just read this in an old Modicon Concept Help File and it may apply here also.

In this application I am obtaining a resistance value from a meter via Modbus RTU (using a ProSoft module) and wanting to display the final value on the PV 1000. For instance, if the result is -2.5, it rounds up to -2. Simple question I think. When sending data out of the ProSoft module or gateway, the Float value will have been stored in the memory as two 16 bit integers, rather than a single float. Use a SCL instruction in function block and configure your card raw values to be 4000-20000 for example and then have your InEUMin and InEUMax set to whatever they are and then your InRawMin set to 4000 and InRawMax set to 20000 then use IE2C.ChXData as your In.

Check the user manual of your specific module for more information on swap codes. 0000014443 00000 n The structure within a PLC can be broken down into 16 distinct booleans which correlates to the fact that an integer is 16 bits. If you assumed they would be zeroed out, that's "unexpected" to you. The numbers were all there in a small array.. what could go wrong? If the result is 2.5, it rounds down to 2. So 2.5 rounds to 2 and -2.5 to -2. This is moving the other direction correct? Because MrPLC.com is not an authorized distributor of this product, the Original Manufacturers warranty does not apply.

How to convert an array of characters into a string in Studio 5000 What is the best way to take a DINT vale and convert it to a Real (floating point). I imagine that these functions take the bottom 16 bits of each value and transfer them exactly. In this tutorial, were exploring the data structures that are at the base of PLC programming and go over the key usages of the booleans, integers and double integers.
