No, but you could scan your sequence code for the reference cd /opt/fox/ciocfg grep AUTDSR */*.s Repeat on each host. There is an obscure case where the parameter to be changed is stored in a SN00xx parameter. This approach won't work in that case. However, you could use getpars to examine the SN00xx parameters. Hope this helps.

The AUTDSR parameter is not linked. However, if I set AUTDSR to 1, (i.e. open the valve), something (a sequence perhaps) sets the AUTDSR to 0. (closes valve) Is there a means of "trapping" this call so as to identify what is closing this valve. Thank you for your assistance.
