LostPatrol Posts: 32 Rating: (0)	Hello All, I'm trying to read a VFD drive speed. The speed resides on byte (for example) I263.0-I263.7 How do I convert these bits to decimal? Thanks,

yy1 Posts: 535 Rating: (112)	Dear LostPatrol, to read a byte in STL you can use the load-instruction: [code] L IB 263 [/code] IB263 can also be used as operand for other instructions / languages. To watch the value in decimal, you can use the 'monitor / modify variables' application. Add a line with address IB 263 and display format 'DEC' Hope this helps. Best regards, yy1

Best regards, yy1 In addition to this , you can load the byte data to decimal data i.e. L IB263 // Byte data from Drive T MW150 // Decimal Data
