FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What is the default data rate for the expansion bus communication on the ETM001?

A: The default expansion bus data rate is 250 kilobits per second.

Wiring & Installation:

Q: What determines the maximum overall cable length supported by the expansion system?

A: The maximum length depends on the receiver module: 750 meters for all isolated ERM001 modules.

Troubleshooting & Compatibility:

Q: What does the EXP TX LED indicator signify when it is blinking during normal operation?

A: The EXP TX LED blinks to indicate active communication between the expansion transmitter and bus receiver modules.

Replacement & Upgrades:

Q: Is it possible to increase the expansion bus data rate above the default speed in a PLC system?

A: The rate can be configured to 1 megabit per second if total cable length is under 250 meters and no non-isolated receiver modules are used.
