Hi All I am trying to setup remote access to a mitsubishi A1s Plc via a Westermo Modem. Plc Card: A1SJ71UC24-R2 Modem: Westermo TDW-33. I am trying to comm through GPP Win but keep getting failure at the point in which GPP Win gets to "Handling password of TEL". Anyone got experiance of...

Solenoid valves SMC SY3120-5LOU-C6. Standard 5 Port Sov i guess bi-directional but not 100%. Many Thanks for your help on this subject.

HI Terje That is the case if the outlet valve was spring operated to close. But what if the valve needs pressure to shut. Cheers

Hi all i am from the electrical forumn but i am puzzled with a pneumatic question. I have a dump valve at the bottom of a vessel which is energise to dump. We have to control this valve via two 5 port solenoids. How do i configure the ports if possible for each solenoid to dump independant or...

cjw32 Thankyou so much for replying, it seems that this subject is causing many people to bury their head in the sand.

Could someone please put me right here on the use of analogue signals. Statement for an IDC book on Saftey Instrumented Systems "1oo2 is dual channel which has a fault tolerance value of 1 because if one channel has a dangerous hidden fault, protection is still available via the redundant...

All Thanks for you reply much appreciated.

Thanks for the replies. Ozmosis i think it does measure the magnetising current, but the drive didn't like autotune in the stationary mode. It wasn't until i put the mag current setpoint in from another drive on an identical motor on the other plant that it would run correctly.

I recently had some experiance with Eurotherm / Parker 690 VSD drives. To run in Vector control it required a auto tune. But the autotune had to be selected to perform this in stationary mode due to the load. If autotune in stationary mode the drive required the magnatizing current from the...

I am considering a training program that the above company runs, Advanced Diploma in Industrial Automation. I have dealt with this company purchasing some good books. Does anyone have feedback on the company in way of training. Your experiance wood be appreciated www.idc-online.com

I have a 200kva generator with two 12v 125Ah lead acid batteries. I need to install a charger to maintain the batteries. My question is could anyone recommend a good supplier of battery charger. Also if the generator when running charges the batteries does the charger need to be disconnected...

So can i put this question, if i understand this correctly. If the supply is increased to say 500v to a 600v normal drive the motor will see a higher voltage due to the increase in the dc bus level. But say i use an active front end drive instead at 500v could you lower the voltage to the motor...

HI The application is to control two remote boreholes that are remote fron the control section. The applications requires PID control. Signals required 2 Analogue 2-20ma 10 Digial I/o for each borehole. The customer does not want Plc control so the control for PID is to be via a ABB...

I have an application to run I/O and analogue between two building over a fibre optic link. Does anyone have a recommended solution. The client has expressed that he does not want a plc solution.(Same)

Hi all, Have read the posts but no body has gone on to the subject of the line contactor being used for emergency stop . What would you size the bypass contator for AC3 Or AC1 if the line contactor was dropped out while running at full speed. Surely the bypass contactor would have to be rated...
