Phi,

Are any of the motors (real or soft) doing retries?

How does the $(P)-DMOV record's behavior differ between the 1st relative move, which succeeds, and the 2nd relative move, which misbehaves?

Hi,

I am using RLV for relative motion with a soft channel. When I issue a caput command with a value of 2 to my soft channel, $(P), to move the other real motors, they move by 2 mm. However, when I repeat the caput command with the value 2 to my soft channel for the second time, the motors move by 7*2=14 mm instead of 2 mm. Please advise.

Thank you,
Phi
