Human Factors; Weather
[We] departed DFW 17R via DARTZ6 RNAV departure. The FO was the flying pilot; and I was the pilot monitoring. Prior to TREXX at approximately 3000 ft we received a TA. The intruder aircraft was at a lower altitude and to our right (west). Regional Departure told the intruder aircraft to turn; I do not remember the instructions. The intruder aircraft kept flying to the east southeast and climbing. Our TCAS alerted a TA. The TCAS indicated the aircraft was three hundred below our altitude and climbing. I told the FO to increase his climb rate. At minus two hundred feet ATC issued us an immediate left turn to 140 heading. By the time we started the turn; on our TCAS the intruder aircraft symbol and our aircraft symbol were touching. The TCAS indicated one hundred feet difference. Once we were into the turn the conflict was resolved. We continued on the 140 heading until departure cleared us back to the DARTZ6 departure. I believe [the other aircraft] departed 18L; but had 17R loaded into their FMS. I should've had the FO turn sooner than we did. I should have been more proactive; but the event took place in a short period of time. One of the problems was we never received a RA alert. That may be due to our altitude.
[We] departed Rwy 17R at DFW airport. The flight was cleared via and flying the the DARTZ6 RNAV departure. At approximately 3000 MSL and in instrument meteorological conditions; the flight crew was alerted to an intruder aircraft via an aural TCAS warning. This warning also changed the vertical profile display in each pilot's MFD to the TCAS display; allowing us to visually see the location of the intruding aircraft. The intruding aircraft initially presented at the four o'clock position and 300 feet below. At approximately the same time; the ATC controller issued instructions to [the other aircraft] to begin an immediate right turn. The crew replied that they were experiencing winds of 80 kts. At that time; the ATC controller issued instructions to [us] to execute an immediate left turn to a heading of 140 degrees. I immediately placed the aircraft in a left hand turn; and received one annunciation of the automated 'bank angle' aural alert. I then reset the bank angle to 30 degrees and held that angle until rolling out on a heading of 140 degrees. During cruise; CA advised operations via ACARS of the incident.
