Discrete PID reg. sample time and Solver options

I want to ask whether the sample times (1 inside the discrete PID governor and the another inside the configuration parameters ->Solver options-> Fixed-Step size) must be the same. I would like to have Solver option sample time: 0.001 but my discrete PID has 0.1. Unfortunately when I run simulation I get an error message and to avoid error I need to decrease my PID sample time to 0.001 but I don't want that.

Is there any other way to solve this out?

These 2 sampling times don't have to be the same. What is the error message you are getting?

[Robin Beene]

I get error for proportional,derivation and integration gain "The sample time 0.1 of 'PELTON/Discrete PID Controller1/Derivative Gain' at input port 1 is different from the sample time [0, 0] of 'PELTON/Sum1' at output port 1. Consider inserting a Rate Transition block between the two ports. Alternatively, you can control the diagnostic action for unspecified rate transitions on the Sample Time Diagnostics pane of the Configuration Parameters dialog box."

Try inserting a rate transition block like the tool says.

I did and it worked :P But I'm not sure does it make any difference to my results. Does the Rate transition block has any influence on my simulation results?
