are you talking about a powerflex drive by any chance?

maybe someone who knows more about RSLinx could tell us if there is some security options would could restrict access.

ah ok so maybe you could restrict the IP addresses on windows?

Someone may correct me but i dont think this is possible, i can see why you are asking this but this may cause you more problems in the future if you wan to connect to a different controller, could you provide a list of the IP addresses for each controller for the maintenance staff and give training on how to make sure they have set the right path and how to use the software? if they cant make any changes then i dont see how this can cause any problems.

We have a depositing machine which uses a linear displacement transducer to measure piston stroke, this allows control of how much product is deposited, with limit switches for min and max as reference points

Agree with this probably the easiest way, we have a FX3U with 6 HMIs connected using unmanaged switch and Ethernet card on FX3U

Good afternoon,  I am having some issues getting my head around how a system is working at my work, There is a machine (FX2N) connected to a Beijer E1101 (RS-485/RS-422) and also the Q00JCPU which is also connected by Ethernet to the E1101, now the machine and Q00JCPU are separate they do share some data. could anyone help me shed some light into how this works i have attached some screen shots to show the ladder and can provide more information if anyone requires, there are two different programs you can see the program from the top of the picture  

Thanks for the reply thats great i didn't realise the e1101 had this function for data exchange makes more sense now

what i need some help with is the trigger signal which is pulsed every second could some please explain the purpose of M630   Thanks is advance

Cheers Pop, I am just going to use the system clock for this. Thanks for all your help Regards Matt

Good morning all, I have been tasked with translating an old s5 to something more modern i have only a printed version of the program in STL and ladder but i have a section of STL which has no ladder equivalent and not sure how it should be drawn. The STL looks like this as one segment :A I0.5 :AN F1.6 := F1.7 :A  I0.5 := F1.6 So i have AND I0.5 ANDNOT F1.6 to coil F1.7 then AND I0.5 to coil F1.6 is this just drawn as two separate lines? Sorry if this is a simple question just not programmed with siemens before Regards Matt    

thanks for the info pop, the only flag being used in the program elsewhere is F 2.0 so this flag will pulse from off to on every 500ms? this would make sense as F2.0 is part of a rung which switches an indication lamp on, under a fault condition the lamp should flash so this pulse generator must make the lamp flash. thanks for your help matt

Ok thanks for alll the replies, i have one more issue this time with Some code which looks like it may be some sort of pulse generator here is the STL :AN F 2.2 :L KT 005.1 :SD T 31 :A T 31 := F 2.2 :A F 2.2 :AN F 2.1 :S F 2.0 :A F 2.2 :A F 2.1 :R F 2.0 :AN F 2.2 :A F 2.0 :S F 2.1 :AN F 2.2 :AN F 2.0 :R F 2.1 :BE   Regards matt

Thanks for the explanation POP seeing it like this has help me make sense of the code i have here. 

ah ok that makes sense now,  thanks for the help i can get on with this conversion now.

Ah right so any  STL like this is for a one shot coil?

Thanks man   matt
