EMERSONDeltaV™ Controller Redundancy

System Compatibility M-series, S-series and SZ controllers are all supported on DeltaV v12.3 and beyond. PK Controllers are supported on DeltaV v14.3 and beyond. For detailed version compatibility see the Prerequisites section below. Redundant controller pairs must be of the same series. For example, M-series and S-series controllers cannot be connected together as a redundant pair. Although an SX controller can operate as a standby controller to an SQ active controller, it is recommended that both the active and standby controllers be of the same hardware. The SQ may not have sufficient memory or CPU capacity to accept the configuration that runs in an SX controller. This applies for MX and MQ controllers as well, only mix controller types as a temporary condition during a hardware upgrade. The MQ, MX, SQ, SX and PK Controllers are all capable of redundancy. For more information on these controllers, refer to the respective controller product data sheet. SZ Controllers are also capable of redundancy. For more information on this controller, refer to the DeltaV SIS Electronic Marshalling or DeltaV SIS IS Electronic Marshalling product data sheets.

Ordering Information

Prerequisites „ S-series SQ and SX Controllers require DeltaV v11.3.1 or later. „ S-series SZ Controllers require DeltaV v12.3 or later. „ M-series MX Controllers require DeltaV v10.3 or later. „ M-series MQ Controllers require DeltaV v11.3.1 or later. „ PK Controllers require DeltaV v14.3 or later. „ Each controller in a redundant pair must have its own dedicated control network communications. (not needed on SZ and PK Controllers). „ Each controller in a redundant pair requires a dedicated system power supply on the same 2-wide carrier (not needed on SZ and PK Controllers).
