I am using a sm2315dt'I/o ports as an outputs to energizade some selenoids, their initial states have to be 0 because at the begining of the program i turn off all the ports, but here is the problem, everytime I turn on the motor their states are 1 for few seconds activating the selenoids, is it posible to avoid that?
pd: I/O ports activate some transistors which turn on the selenoids.

This is hard to avoid. One approach is to use a time delay relay or another output to enable power to the solenoid circuits.

we already fix the problem, we have to use some voltage divisors along with some diodes at their respective transistor's base
