Hi! 1.) Yes, that's correct. Respect the colours from the table (if you use a standard PB DP cable) 2.) You could use an active terminator, e,g. like this: According to the doc, you have +5V and Gnd at 54 and 55, so you could do it yourself: http://www.profibus.felser.ch/en/index.html?der_busabschluss_fuer_rs485.htm |

Hi! Not quite. See the attachment. I suppose that the Siemens stuff is in an electrical cabinet. I made a suggestion to put the EH devices in the middle of the PB chain so you do not have to deal with the termination. The standard Siemens PB connector (and the devices) solves that issue. However, that means that you will have go with a PB cable from the cabinet to one EH device, from there to the other one and than back to the cabinet. https://support.industry.siemens.com/cs/pd/428468?pdti=td&lc=en-WW |
