Hi I have a vpn set up to a 4g router running a small CIP station with a cp1-el plc and a NS 10 touch screen. I can program and monitor the plc but i can not program the touch screen. I have tried directly to the ip and fins address of the screen and via the plc but neither work. has any one got any other ideas or an alternate programming method perhaps? I can ftp to the screen and I can view its web page so it is likely something more sinister like the mobile network messing with packets or something. I'm wondering if I can format a memory card and ftp files to it to reprogram the screen or something ?    

Hi in previous times i made a plc program with hostlink to connect two cp1L-20 plcs together which has been working well for years, problem i now have is is that the system was previously using I/O to control a danfoss VSD. I have made a program to talk to the danfoss drive using modbus using rs232 (no protocol)  but talking to the other PLC with modbus is proving troublesome to fit the code in the plc. Is there some way I can use hostlink and modbus at the same time ? so the slave plc and the drive will havg off the same cif12 

I'm having a problem with a NS screen web interface working over a vpn over the mobile network (4g LTE) It takes 10-15 seconds to refresh the page and you can see it doing it a line at a time. I have changed it to gray scale and it is much better but still not good. It works when local with out issue and over the internet but not over mobile internet. I'm guesing it is some sort of buffer issue.   Of note I can monitor and program the plc over the same mobile network with out issue but i cant program the NS over the VPN/ mobile network it just fails.        

I think this might be the easiest option.

Cool thanks 1.43 defiantly asks for a dx11 capable graphics card on install, I might Jusy bite the bullet and buy a gtx 7 series gpu then I will have no issues.

Yes I'm doing that in another part of the code not in the sample. But i have found my problem it uses a proportional band not gain i found this after a second read of the instruction manual, I did not realize this it is kind of a bit odd way of doing it. I was winding up the setting when I should of lowered it to make make the regulation tighter I have it sorted now thanks.  

I'm having issues getting the PIDAT function to work It just does not seem to regulate and I dont know what I'm doing wrong.     pidat.cxp

Correct yes the MAB221 sorry I found it in another manual under programming examples you have to set the serial port settings in the PLC Settings menu for serial 1 to 115200 7,2,E HOSTLINK to make the analogue option board work in the first expansion port.

hi In the manuals currently on the australian edata site they don't show you what to set the serial port to to enable an option board.   I know in the cp1l you could set the serial settings to 115200 or something  or switch the dip switch under the programming cover.   In the cp2e there is no dip switches and this and this info seems to be missing from the user manual. Any one have any idea ?

Are you using the easy master function blocks or your own code ?  

Are any of the NA series HMI's daylight readable I could not find this information on Edata? I have a setup with a NB and CP1L it is installed outdoor with a hood over it and it is basically unreadable in bright and shows reflections when users are wearing HI Vis work gear. I'm wondering if I switch to Sysmac based PLC and NA will it be any better as it is a significant jump in price? I'd like to avoid the route of a PC based HMI and scada package like ignition because of the cost.

I'm using a mixture of NB and NS screens currently and possibly in the future ignition scada. That is one option I guess but it is screen dependant and would be nice to do it in the plc.      

Hi I have flow meters and have them counting up to a value and stopping a pump.   it all works but the display on the hmi counts up in decimal places because of the scale factor of the flow meters. To scale them because of inacuracy I basically multiply what I want to count to by 1000 and i basically add for every pulse of the flow meters a value between 1500 and 500 to count to scale the flow meters then compair the two to stop the pump if the count is equal to or greater than the dialed in amount. Is there an easy way to round this value to the nearest bigest 10's value? I'm guessing convert to a floating point use the FIXL instruction? is there an easy way im missing as I could not seem to find a rounding instruction?
