More Information

Overview Manuals Ports Messages Versions Installation

Features:

  • Expands a Series 90-30 controller so multiple SNP masters can reach PLC reference data.
  • Handles SNP requests up to 10,000 bytes and datagrams up to 250 bytes.
  • Introduces additional engineering and protocol functions across documented hardware revisions.
Revision B and later add LogicMaster communications for programming and data access, while the earlier Revision A hardware does not provide that capability.

Revision C introduces SNP-X utilization, and Revision D adds support for the Change SNP ID communication request, making installed hardware identity important during replacement.

The interface serves program and reference-table access but deliberately excludes transfer of the Series 90-30 system configuration, preserving a clear boundary around its engineering role.

For the legacy Horner APG HE693SNP900 SNP Interface Module, Apter Power offers quotation assistance and access to official Horner product documentation.

Serial Interface Setup for HE693SNP900

  • Electrical mode: The selected RS-232 or RS-485 setting matches the master port and installed cable network.
  • Baud setting: Both endpoints use the same supported communication rate up to 19.2 kbaud.
  • SNP identity: The configured slave ID remains unique and consistent with the master application.
  • Topology limit: Radio-modem operation is excluded from the supported interface arrangements.

HE693SNP900 Data-Access Boundaries

  • Reference access: An SNP master reaches PLC reference data through the added slave path as if connected to the native controller interface.
  • Large request: A standard message can address a data block of as much as 10,000 bytes.
  • Datagram limit: Datagram requests use a separate 250-byte maximum that cannot be treated as the normal message ceiling.
  • Configuration exclusion: The port is not used to transfer the Series 90-30 hardware configuration.

Functional Evolution of HE693SNP900

  • Revision A: The initial hardware does not communicate with LogicMaster 90.
  • Revision B: Programming and reference-table access through LogicMaster become available.
  • Revision C: The interface adds use of the SNP-X protocol.
  • Revision D: The Change SNP ID communication request becomes supported.

Series 90-30 Integration of HE693SNP900

  • Free slot: The interface occupies an available position in the local PLC backplane.
  • CPU baseline: Controller firmware meets the minimum version required for module operation and engineering-tool access.
  • Power allowance: The rack budget includes both steady 5 VDC demand and the brief startup inrush.
  • Startup sequence: Port parameters are configured before the SNP master application is connected and started.
Description
An additional SNP slave connection is provided to a GE Fanuc Series 90-30 PLC by the Horner APG HE693SNP900, allowing another compatible master to reach controller reference data.

The serial path on HE693SNP900 can be arranged for RS-232 or RS-485 signaling at rates through 19.2 kbaud. Standard SNP requests and datagrams use different transfer limits, which must be respected by the connected master application.

Installation uses a free local backplane position and a compatible CPU revision. Port parameters are established with the Hand-Held Programmer or LogicMaster 90 before the master is placed into service.

Hardware level affects engineering access and protocol behavior on HE693SNP900: later builds introduce LogicMaster communication, SNP-X use and Change SNP ID support. Replacement therefore requires the complete installed revision to be identified.

Technical notes
HE693SNP900 is an SNP slave path and does not transfer the Series 90-30 hardware configuration; its engineering access is limited to supported program and reference data.

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.
Why can an HE693SNP900 communicate with a hand-held programmer but not LogicMaster 90?
HE693SNP900 LogicMaster operation depends on the installed hardware revision and a compatible PLC CPU. Revision A lacks LogicMaster support, while later revisions add it.
Why can HE693SNP900 exchange reference data but not copy the PLC hardware configuration?
HE693SNP900 provides supported program and reference-table access through its SNP slave path. Series 90-30 system-configuration transfer is outside that interface function.
Which serial mode should be selected for an HE693SNP900 master connection?
Configure HE693SNP900 for RS-232 or RS-485 to match the master interface, cable topology, distance, and electrical signaling used by the installed SNP link.
Why does an HE693SNP900 fail after installation in an older CPU rack?
HE693SNP900 requires PLC CPU version 5.01 or later, and LogicMaster use requires version 6.50 or later. Confirm the controller version before changing port parameters.
Why does a large datagram request fail through HE693SNP900 even though a normal SNP request succeeds?
HE693SNP900 allows a standard SNP request to access up to 10,000 bytes, but a datagram request is limited to 250 bytes and must be divided when it exceeds that boundary.
Can HE693SNP900 be used with a radio modem?
No. HE693SNP900 does not support radio-modem operation; use only the documented SNP serial interface arrangements.
What should be checked when an HE693SNP900 causes a backplane power warning?
Include the HE693SNP900 steady 200 mA at 5 VDC and 300 mA three-millisecond inrush in the rack power budget, together with every other installed module.
