I have PH running on two systems, my primary and my backup computer. I want to make the macros/code as transparent as possible. I have code to determine which system it’s running on, and it makes various adjustments accordingly. The last remaining one is to change the port for the CM11A controller. Currently I have to manually go to PH explorer/Setup/Controllers and click “settings” and change the port number then click “DONE”.
So, I got this brain storm to do a direct SQL to automatically change the port.
Let’s say I want to change the X10 controller port from 3 to 5.
If I execute the following direct SQL
Ph_sql(1," select * from ctlrparms where parm = 'port' ")
Formula evaluates to: data(CM11A_1”,”port”,”3”,)
Ok, all good. Port = 3
Then when I do the update:
Ph_sql( 1, “update ctlrparms set value = 5 where parm = 'port' " )
Formula evaluates to: data()
Seemingly all good, BUT if I go to PH explorer/Setup/Controllers and click “settings” I can see the new port of 5, but when I press “DONE” it locks PH. I have to go to the task manager to end the program.
No matter what change I make, 1 to 1, 3 to 5, it locks PH tight.
When I restart PH, it has the old value, not the new one. Seemingly it didn’t update/flush/write the new value.
Am I doing something wrong?

gg102,
Assuming the ID of your CM11A is "CM11A_1", try this formula instead:
Code:
ph_directsql("update ctlrparms set value = '5' where id = 'CM11A_1' and parm = 'port'")

Hope this helps,
