Integrator_99

Hello Simo99, SFL is the instruction for shifting (moving) bits to the left.  Each time the instruction is executed, it moves the bits in (d) by (n) bits.  I would recommend reviewing the e-Manual Viewer's help file on SFL(P).  Depending on which model of PLC you're working with, you will probably want to monitor the Carry bit in SM700 or SM8022. I write up a quick demo for you.  The ladder loads '59' into D1000 and then shifts it to the left by 3 bits each time SFL is executed. I'm not an expert with SFL but I hope this helps.  

Hello Tarek_Shawki,      I don't have my GX Works open.  Does the FX3 have the EVAL(P)/DEVAL(P) instructions?  You could use those to convert the ASCII value to a FLOAT (probably store the result in a different register than the source value), then convert the FLOAT to an unsigned DWORD.

Hello Beny236,      I've used the MR-J4 a bit but I'm not an expert with them.  Have you configured the parameters in MR Configurator2?  There's an option in Function Display > Component Parts > Battery > Enabled (Used in ABS pos. detect system).      What fault code does the Amp display?

Hello A.J,      There are lots of ways to do this: One approach would be to use a 1min timer.  When the timer completes, lower the valve and start the timer again. (Timers like TON, TOF, OUT_T, etc.) Another approach would be to use PLC's internal system clock (SD214 - depending on PLC) and lower the valve when the value changes.      Which PLC are you working with and what language are you programming in (ladder, FBD, ST)?
