Hi guys, Made it to Friday!! 
Working on a project for a customer that has an existing FT View SE 7.0 HMI. The HMI has several PID loops on valves that when when clicked on open a PID faceplate passing the parameter TIC4016 or so. This works great but in the FP there is a trend popup that does not inherit the TIC4016 parameter to load the proper PV, SP,CV points. Can this be done?
I tried adding a second command to the touch release that would toggle a bit in the logic that moves the string "TIC4016" to a common holding string "StringHolder" and then call it and have the goto trend button load a PID Trend screen and call parameter #1=StringHolder to use the value now stored in StringHolder and read it as #1=TIC4016, or #1=TIT1010 but the trend will not accept the tag replacement. Any ideas?
Without the parameter it works as #1=TIC4016
I've tried the following:
#1=StringHolder
#1=[StringHolder]
#1={Plant[CLX]}StringHolder
#1={Plant[CLX]}StringHolder.Value
#1={Plant[CLX]}StringHolder\StringHolder
#1={Plant[CLX]}StringHolder\StringHolder.Value
Clearly I'm grasping at straws with the syntax here and it may not be possible. I read in a similar thread where someone loaded the trend with the PID FP and used the second button to toggle visibility of the trend. But I'm really curious to see if it can be done cleaner and using less real estate (even if invisible.)
Thanks,
