More Information

Overview Manuals Direct Service Port Factory LAN Client Limits Product Applications

Features:

  • Separate network roles: service and factory LAN ports serve different connection tasks
  • Direct RobotStudio access: the service port supports a locally attached PC
  • Defined successor: ABB documents DSQC1000 as the replacement computer unit
DSQC 639 distinguishes local service access from production-network communication at the controller hardware level.

Its client limits and address behavior make port choice part of troubleshooting, not a matter of interchangeable Ethernet sockets.

A migration record should connect backups, network ownership, software, options, and the ABB DSQC1000 replacement process.

  • PC connection: attach one service computer directly as documented
  • Address behavior: retain the fixed controller and DHCP client arrangement
  • Local diagnosis: use RobotStudio without treating the port as factory LAN
  • Production network: preserve the public controller connection and addressing
  • Port ownership: label every cable before computer replacement
  • Security context: restore only the approved plant-network configuration
  • Session inventory: count RobotStudio, FlexPendant, LAN, and FTP clients
  • Connection symptom: check occupied sessions before blaming Ethernet hardware
  • Migration record: reproduce required access after the DSQC1000 replacement
  • IRC5 controller computing: run an established RobotWare robot system
  • RobotStudio service: provide direct local engineering access
  • Legacy-network maintenance: preserve factory LAN communication during controlled computer migration
Description
DSQC 639 is an earlier ABB IRC5 computer unit documented with separate service and factory LAN interfaces. The service port is intended for direct RobotStudio access, while the factory LAN side connects the controller to the wider installation network.

On DSQC 639, the service interface uses a fixed controller address and can provide DHCP settings to a directly connected PC. ABB documents different connection limits for service, LAN, FlexPendant, and FTP use, so reachable Ethernet does not guarantee another client session.

Replacement planning for DSQC 639 should preserve the RobotWare backup, controller identity, network addressing, connected clients, fieldbus hardware, and port ownership. ABB identifies DSQC1000 as the replacement computer, but migration still requires the official procedure for the installed controller.

Technical notes
Do not move the factory network cable to the DSQC 639 service port as a troubleshooting shortcut. That port is designed for a direct PC, uses a fixed controller address, and supplies DHCP to the client; record LAN ownership, active sessions, RobotWare, options, and backup before following ABB's DSQC1000 replacement procedure.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which Ethernet port should a technician use for direct PC access to DSQC 639?
Use the service port. ABB configures it with a fixed controller address and DHCP for one directly connected service computer.
Can the service and factory LAN ports on DSQC 639 be treated as interchangeable?
No. The service port is for direct local access, while the LAN port is the controller's public factory-network interface with plant-assigned settings.
Why can a fourth LAN client fail to reach DSQC 639 while three clients remain connected?
ABB limits the LAN port to three connected network clients. Close an unused session before diagnosing a computer or Ethernet fault.
What replacement does ABB document for DSQC 639?
ABB identifies DSQC1000 as the replacement computer unit. Follow the official installed-controller procedure rather than treating the newer hardware as an unplanned drop-in change.
Can two service laptops connect to DSQC 639 at the same time?
Not through the service port. ABB limits that port to one connected client, so disconnect the existing service session before testing another laptop.
Why can a fifth FTP transfer fail on DSQC 639 even while RobotStudio still connects?
ABB limits concurrently connected FTP clients to four. Close stale FTP sessions before changing controller network settings or replacing the computer.
