which OB must we use in S7-1200


"The idea is to add an integrated value from a scaled analogue signal, to a register every 100ms.At 60m³/h, the register should count up to 1 every minute, but it counts erratically. Never the same value, but always a lot more (10-20)"This works in a 300 using OB35 at 100ms.

Any way to rectify this? Please see attached.
