More Information

Overview Manuals Applications Compatibility Communication Configuration

Features:

  • The ordered configuration is the Schneider Modicon hot-standby option module made specifically for 984 slot-mount PLC systems.
  • In service, the hardware supports the controller-to-controller standby arrangement used to maintain control availability in the matching 984 architecture.
  • Correct selection depends on only the 984 slot-mount family; AM-S911-000 and AM-R911-000 are chassis-mount modules and do not fit.
The current order is identified by the complete AS-S911-800 marking and its documented relationship to Modicon 984.

The hardware is used in redundant Modicon 984 installations that use slot-mount rather than chassis-mount hardware, where it supports the controller-to-controller standby arrangement used to maintain control availability in the matching 984 architecture.

Installation planning must account for only the 984 slot-mount family; AM-S911-000 and AM-R911-000 are chassis-mount modules and do not fit. never cross-connect the slot-mount AS-S911-800 with chassis-mount S911/R911 hardware; verify both redundant sides before service

Availability is confirmed against the complete model, revision, quantity and delivery destination.
Verified resources for Schneider Electric AS-S911-800:Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Supports redundant Modicon 984 installations that use slot-mount rather than chassis-mount hardware without changing the documented host architecture.
  • Serves maintenance teams restoring the original Modicon 984 signal, control or power path.
  • Fits modernization planning when the existing installation must remain operational while a long-term migration is evaluated.
  • System matching is governed by only the 984 slot-mount family; AM-S911-000 and AM-R911-000 are chassis-mount modules and do not fit.
  • The surrounding Modicon 984 hardware must retain the connector, addressing and project relationships documented for this order code.
  • A cross-family or partial-number substitution is not approved unless the OEM service record explicitly defines it against AM-R911-000 for chassis-mount systems.
  • The primary connection boundary is the slot-mount 984 backplane and the hot-standby interconnection defined by the legacy system design.
  • Cable, terminal and network assignments must follow the host-system drawing rather than physical connector similarity.
  • Signal integrity depends on preserving the documented grounding, shielding, termination and topology for this hardware path.
  • Configuration data belongs to the installed Modicon 984 project and should be backed up before hardware removal.
  • Revision, firmware, address and option settings must be reviewed together with the complete order number.
  • Commissioning should load only a validated project or parameter set and then confirm the intended operating state.
Description
Schneider Electric AS-S911-800 provides the Schneider Modicon hot-standby option module made specifically for 984 slot-mount PLC systems. The complete order identity ties this hardware to the Modicon 984 platform rather than to a visually similar device.

For plant operation, it supports the controller-to-controller standby arrangement used to maintain control availability in the matching 984 architecture. Its principal connection boundary is the slot-mount 984 backplane and the hot-standby interconnection defined by the legacy system design, making the unit suitable for redundant Modicon 984 installations that use slot-mount rather than chassis-mount hardware.

To avoid a configuration mismatch, inspect only the 984 slot-mount family; AM-S911-000 and AM-R911-000 are chassis-mount modules and do not fit. Never cross-connect the slot-mount AS-S911-800 with chassis-mount S911/R911 hardware; verify both redundant sides before service

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 evidence hot standby module validates the exact AS-S911-800 configuration?
Use the complete model and the defining configuration: the Schneider Modicon hot-standby option module made specifically for 984 slot-mount PLC systems. Include every suffix and secondary assembly number shown on the nameplate.
Which installed-system evidence is decisive for matching AS-S911-800 as a hot standby module?
Confirm only the 984 slot-mount family; AM-S911-000 and AM-R911-000 are chassis-mount modules and do not fit. The match must be made to the installed Modicon 984 records, not only to appearance.
Where does AS-S911-800 perform its documented hot standby module duty?
The documented application is redundant Modicon 984 installations that use slot-mount rather than chassis-mount hardware. In service, it supports the controller-to-controller standby arrangement used to maintain control availability in the matching 984 architecture.
How should a buyer establish the present supply route for AS-S911-800?
The OEM lifecycle is recorded as Discontinued / Obsolete by OEM. Apter Power confirms actual condition, available quantity, lead time and destination before issuing a dated offer.
What field condition can prevent a like-for-like AS-S911-800 replacement?
Never cross-connect the slot-mount AS-S911-800 with chassis-mount S911/R911 hardware; verify both redundant sides before service Compare the proposed unit with AM-R911-000 for chassis-mount systems only through official service documentation.
Which records should accompany a AS-S911-800 datasheet and quotation request?
Send clear nameplate photos, host model, revision, wiring or slot reference, required quantity, destination and requested delivery date so the exact datasheet and quotation can be matched.
