QTS-CLX-APACS Module Overview
The QTS-CLX-APACS connects a ControlLogix controller to an APACS ® IOBUS
network.
Use the QTS-CLX-APACS to migrate APACS systems to ControlLogix controllers. You
can retain the APACS I/O as the first step in the migration.
The module acts as either a monitor or as a master on the APACS IOBUS. You select the
mode by downloading different firmware to the module, using the Windows configuration
programs provided.
In monitor mode, the QTS-CLX-APACS sends APACS I/O input and output data to input
data in the ControlLogix. It cannot transmit on the bus.
In master mode, the ControlLogix sends output data to the QTS-CLX-APACS, which then
transmits it as output data on the APACS IOBUS. The QTS-CLX-APACS sends APACS
input data to input data in the ControlLogix.
The QTS-CLX-APACS:
• supports IOBUS cable redundancy
• supports up to the maximum of 39 I/O cards allowed by the APACS IOBUS in a
maximum of 4 MODULRACS
The QTS-CLX-APACS communicates with the ControlLogix processor using scheduled
connections. You configure the module in RSLogix 5000 (v19 or greater) with up to:
• 10 I/O connections, 9 for data and 1 for status
