Controlling 2 position double acting 24VDC solenoid

-

does know proper signals give smc sy3240 24vdc 2 position double acting solenoid?  has 24vdc connector on both sides.  want control pneumatic actuator - able have actuator extend , retract on signal.  using 2 pins on arduino control 2 relays control 24vdc input solenoids ( 1 relay extend side , 1 relay retract side of double acting solenoid).  assumed give 24vdc pulse 1 side 100 milliseconds or , when want change position, give 24vdc pulse other side.  in practice actuator extend first pulse, not retract when pulsed solenoid on other side.  idea's.

link datasheet?

i have id (primary key) set bigint in sql server. have query following: where whateverid = <cfqueryparam cfsqltype="cf_sql_integer" value="#url.id#"> i got invalid data type it. tried: where whateverid = <cfqueryparam cfsqltype="cf_sql_bigint" value="#url.id#"> i still got invalid data type it. tried: where whateverid = <cfqueryparam cfsqltype="cf_sql_int" value="#url.id#"> and worked. the weird thing cf_sql_int not listed being accepted: http://www.adobe.com/livedocs/coldfusion/5.0/cfml_reference/tags79.htm can explain me. > whateverid = <cfqueryparam cfsqltype="cf_sql_bigint" value="#url.id#"> what value of #url.id#? had no problems either using cf8. > weird thing cf_sql_int not listed being accepted: iirc, when pass in invalid sql type cf uses default: cf_sql_char, accepts anything. ms sql implicit convert() right type , why works.
