[quote user="starimost"] I am new at programming Simatic S7 and need little help. I shall use load cell to weigh one Jet fuel tank. It will be 4 load cell under tank. My question is: what components do i have to use in PLS witch is EX, zone 1, and have amplifier of safety barrier in components? I so a little this Siwarex modules, but it is not easy to deside. Thanks in forward I have found some information for you, i haven't found Siwarex modules that may directly be used in Zone 1, but a module in Zone 2 and then used with the SIWAREX IS Ex-barrier might solve your problem.. [;)] This is the ATEX confirmation for the modules Siwarex FTA / FTC / CS / CF / MSfor Zone 2 EG / english / Ex i / 7MH4930* / KEMA 04ATEX1086 X http://support.automation.siemens.com/WW/view/en/22750040 SIWAREX Ex-Cable - 7MH4702-8AF / LI2Y 1 x 2 x 0,75ST + 2 x (2 x 0,34ST) - CY http://support.automation.siemens.com/WW/view/en/17165908 How many load cells can I operate on one SIWAREX IS Ex-barrier? http://support.automation.siemens.com/WW/view/en/17163937 So you may choose from several Siwarex modules, please download for the mentioned Siwarex FTA / FTC / CS / CF / MS modules the handbooks to see what the capabilitys are for this modules and for what kind of system the modules are.
