Will AM-SA85-000 fit a PCI-only host computer?

AM-SA85-000 uses ISA, so a PCI-only slot is not its host interface. Keep it separate from PCI or PCIe Modbus Plus adapter references.

Which driver startup settings are used for AM-SA85-000 in the Q1683 Citect configuration?

That legacy setup uses SA85.SYS with software interrupt 0x5B and /r2, then loads DOS_MP from WINSTART.BAT before Windows. These settings apply to the Citect versions named in Q1683.

How is a second AM-SA85-000 selected in the legacy Citect board form?

The board address must match the board number supplied with the SA85.SYS /n option. The port form then references that board's unique name.

How is a bridged PLC path entered for AM-SA85-000 communication?

Enter the PLC's Modbus Plus route in the I/O-device address field. Q1683 gives a direct node as 1 and a PLC at node 2 through bridge node 5 as 5,2; the route has up to five parts.

Can one AM-SA85-000 virtual port serve more than one Modbus Plus unit?

Yes. Q1683 allows multiple units per virtual port and up to eight ports per board. It recommends a separate virtual port for each unit when maximizing performance.

Should baud rate and parity be entered in the AM-SA85-000 Citect port form?

Q1683 marks baud rate, data bits, stop bits and parity as unused in this MBPLUS port form. Do not apply serial Modbus RTU settings to those fields.

How does AM-SA85-000 string handling avoid byte reversal in the documented Citect setup?

Set MBPLUS StringReverse to 0 for the Q1683 configuration. This keeps the bytes within string words from being swapped; verify the resulting PLC string representation.

What changes when ordering AM-SA85-030 instead of AM-SA85-000?

AM-SA85-030 is the kit containing the AM-SA85-000 single-channel adapter together with a Modbus Plus driver-suite CD. The older AM-SA85-000 supply identity refers to the adapter alone.

Information

Overview Manuals Common Applications Product Precautions

Schneider Electric AM-SA85-000 connects an ISA-equipped host computer to a single Modbus Plus channel. Driver loading, board selection and PLC routing must agree with the host application's documented setup.

Provides the ISA host path into a Modbus Plus network.
Uses board-level address settings alongside application configuration.
Supports addressed PLC communication through the installed SA85 driver.
Separates board identification, virtual ports and destination routing.

For the legacy Citect versions covered by Q1683, the board, port and I/O-device forms form one linked communication chain. Check that chain against the loaded SA85.SYS and DOS_MP components before diagnosing PLC data exchange.

Important Notice: Q1683 describes CitectSCADA 1.00-3.00 settings; its interrupt and timing values are not universal recommendations for other software or operating systems.

Schneider Electric AM-SA85-000 Technical Reference (PDF)Schneider Electric AM-SA85-000 Installation & Commissioning Guide (PDF)

The technical reference identifies the ISA adapter and the legacy driver/configuration fields; the installation guide follows the supported Citect board, port, route and variable-verification sequence.

Legacy Citect PLC accessConnects a supported CitectSCADA host to Modicon PLCs through the documented MBPLUS driver configuration.

Bridged Modbus Plus routesSupports the destination path entered in the I/O-device form when a PLC is reached through a Modbus Plus bridge.

Multi-device pollingAllows multiple Modbus Plus units behind virtual ports, with port allocation matched to the supported host configuration.

ISA workstation renewalRestores the existing single-channel host interface while retaining the applicable address and driver setup.

Verify AM-SA85-000 as the single-channel ISA adapter before host work. Use the driver and application instructions for the installed software; the Q1683 settings describe a legacy Citect environment.

Use an ISA-compatible host; do not treat a PCI SA85 product as the same physical interface.

Retain the on-board memory and station-address settings and check them against the host configuration.

For the Q1683 Citect setup, match SA85.SYS to interrupt 0x5B and the /r2 option.

Load DOS_MP from WINSTART.BAT before starting Windows in the documented legacy setup.

Keep the Citect board address consistent with the SA85.SYS /n identifier when more than one board is installed.

Link each port to the correct board name and each I/O device to the intended port name.

Use the actual five-part PLC route; do not replace a bridged path with only the final PLC node.

Check digital and register addresses plus string byte order against the intended PLC data before enabling application writes.
