6DS1916-8RR

Siemens 6DS1916-8RR is a PCI signal module for PCS 7/TM-OS and PCS 7-OS operator stations. It controls up to three external signaling devices, such as horns, buzzers or lights, and provides three additional binary inputs. A 32-bit PCI bus slot with 5 V signaling is required; the module cannot operate in a 3.3 V PCI slot. The configuration is local to each computer and is not transferred automatically by project duplication.

The hardware watchdog is retriggered cyclically by WinCC Runtime through the driver. If retriggering stops, for example because the computer fails, the watchdog triggers the configured alarm. Audible signals can be acknowledged through software or an external hardware acknowledgment button. The external function signals use isolated relay contacts or optocouplers, and the externally supplied 24 V DC circuit requires customer-provided 1 A protection.

The front 25-pin Sub-D connector carries the signaling and watchdog functions; the 9-pin connector is not used for this application. Message classes and signal tags are assigned to the three physical outputs in the horn configuration. The module requires a suitable product status, such as ES4 or later, and a driver matched to the operating system and WinCC release. Commissioning should test each output, acknowledgment path and watchdog response independently.
