Hi everyone I need assistance concerning connections/settings to connect my transducer (4 wires) to my analog card. first i am working with a current supply generator (4-20mA) to make my tests. 3 configurations are working 1)configuration like picture 1 attached. or like p225 in S7 400module data manual. My generator is in pasive mode, 2 wires, 4-20mA Switch of my card is in "D" position, settings HWconfig are TMF2F and 4-20mA. Result is correct, i read correct value in my VAT. 2) configuration like picture 2 attached. or like p226 in S7 400module data manual. I added +24V power supply in L+ My generator is in active mode, 4 wires, 4-20mA Switch of my card is in "D" position, settings HWconfig are TMF2F and 4-20mA. Result is correct, i read correct value in my VAT. 3)configuration like picture 3 attached. or like p224 in S7 400module data manual. My generator is in pasive mode, 2 wires, 4-20mA Switch of my card is in "D" position, settings HWconfig are TMF2F and 4-20mA. Result is correct, i read correct value in my VAT. - CONCLUSION 1) test n°2 should not work, to put generator in active and card in D position !! 2) any configuration with my card in "C" position (4DMU: current 4-20mA) is working. I have all the time 32767. SO in fact, this mean i cannot put my transducer 4 wires QUESTION: 1) Where is the Mana connector in the card 6ES7431-1KF10-0AB0 ? I found Mana for others card but not for this one. Do i need it? 2) does anyone got an idea or a scheme of how to connect my transducer thanks in advance Attachmentpic123.zip (337 Downloads) |
