Asunto: RE: Illegal Choice PV

I have not used CSS.  However, I suspect that the problem is a confusion between the string value of the PV and the integer value.  bo records have both an integer value (0 or 1) and a string value defined by the ZNAM and ONAM fields, which might be "Off" and "On".  You can send either a number or a string.  But if you send a string it must match either the ZNAM or ONAM fields.  Perhaps you are sending 1 as a string, rather than as a number?

Subject: Illegal Choice PV


Hi there,

I am trying to give value = 1 to a PV (bo) using a boolean button on CSS. When I push the button the action should be write 1 to a PV, but in the Windows IOC it appears the message: "Illegal Choice PV : 'pv name' 1". Why?.

I am using AsynPortDriver to use a variable that matchs with the pv. So, I want to use the value of the variable to block / unblock writing parameters in a LLRF register. If user push the boolean, then I send a 1 to a PV and then I write a C++ loop that if the variable is 1 then block parameters.


Am I explaining correctly?.


Thank you for your help.
