The GE IC693PBS201, also cataloged as the IC693PBS201 Profibus Slave Module, operates as a dedicated hardware component for field network communication interfacing within Series 90-30 platforms. Occupying a single chassis slot, the module acts as a remote communication adapter transferring up to 244 Bytes of input data and 244 Bytes of output data cyclically between local baseplate I/O modules and a centralized Profibus DP master controller.

Backplane Bus Interfacing and Communication Latency

The IC693PBS201 coordinates data transfer across the Series 90-30 parallel backplane to maintain high backplane bus communication velocity during slave cycle execution. Configured using Proficy Machine Edition Logic Developer, the module validates communication status via an internal Slave Status Word. Onboard serial processing handles baud rates up to 12 Mbps while maintaining full firmware flash compatibility for local service updates without disrupting adjacent module hardware operations.

Frequently Asked Questions

Q: What baseplate slot locations are supported for the IC693PBS201?

A: The module can be installed in any available I/O slot across Series 90-30 baseplates, excluding Slot 1 of the CPU baseplate, which is dedicated exclusively to the power supply module.

Q: What are the primary functions of the two 9-pin D-shell communication ports?

A: Port 1 serves as an RS-232 service interface for firmware modifications and local maintenance, while Port 2 provides the primary connection to the external Profibus DP network.

Q: What is the maximum backplane power current draw for this module?

A: The IC693PBS201 draws a nominal 450 mA from the internal 5 VDC backplane logic power rail.

Field Installation Guidelines

  1. Disconnect system rack power and external I/O field power sources prior to inserting or removing the module from the baseplate.
  2. Wear an ESD wrist strap connected to a bare metal enclosure ground point before handling the circuit assembly.
  3. Align the single-slot module card edges with the baseplate slot guides and seat the unit firmly until the rear connector latches engage.
  4. Connect the Profibus network trunk to the 9-pin D-shell slave port using approved shielded cable (e.g., Belden 3079A or Siemens 6XV1), ensuring proper line termination resistors are enabled at both physical ends of the segment.
  5. Supply power to the rack and verify communication status using the diagnostic LED indicators and Proficy Machine Edition configuration software.
