Eurotherm 818 PID Controller Equation

Dear All,

Just a quick question which hopefully someone will be able to shed some light on. I'm doing a troubleshooting exercise on a process controlled
by a Eurotherm 818 PID Controller.

What is the equation for generating the controller output from the MV, SP, PB, Ti and Td parameters ? I know the various forms of PID
controller (e.g. series, parallel, etc), but don't know the specific one that applies to this device.

Any help would be greatly appreciated. Thanks.
