Description
Additional information

The Siemens SIMATIC ET 200S terminal module 6ES7193-4CB20-0AA0 is a terminal module (TM-E) belonging to the ET 200S distributed I/O system family. This specific module serves as a base unit onto which electronic modules are inserted, providing the mechanical and electrical interface between the electronic module and the field wiring. It is part of Siemens' modular ET 200S station architecture, designed for use with PROFIBUS DP or PROFINET-based distributed I/O configurations.

The 6ES7193-4CB20-0AA0 is a TM-E15S24-A1 terminal module that accommodates 2-wire and 4-wire sensor/actuator connections. It features spring-loaded terminals for reliable field wiring connections and supports the hot-swapping of electronic modules without interrupting the bus communication or disconnecting field wiring. The module integrates seamlessly into the ET 200S station rail and provides the necessary power bus and signal bus connections to the inserted electronic module.

The ET 200S terminal modules are widely used in manufacturing automation, process control, and machine building applications where distributed I/O is required close to the field devices. They are particularly suited for automotive assembly lines, packaging machinery, and conveyor systems where modular, scalable I/O architectures reduce wiring complexity and improve system diagnostics. The ability to replace electronic modules without rewiring makes them valuable in high-availability production environments.

Common Diagnostic Codes

Fault Code 1: Station failure – the ET 200S station is not responding on the fieldbus
Check PROFIBUS DP or PROFINET connection, verify bus termination, and confirm the IM (interface module) is powered and correctly configured.
Fault Code 2: Module missing or removed – an electronic module has been removed from a terminal module slot
Re-insert the correct electronic module into the terminal module. Verify module type matches the hardware configuration in the engineering tool (STEP 7 or TIA Portal).
Fault Code 3: Wrong module inserted – the electronic module type does not match the configured module
Remove the incorrect module and insert the module type specified in the hardware configuration. Update the configuration if a module change is intentional.
Fault Code 4: Short circuit on output channel – a digital or analog output channel has detected a short circuit
Disconnect the field wiring from the affected terminal module, identify and resolve the short circuit in the field, then reconnect and reset the fault.
Fault Code 5: Supply voltage missing or out of range – the 24 V DC supply to the power module or terminal module is absent or below threshold
Measure the 24 V DC supply at the power module terminals. Check fuses, power supply unit output, and wiring continuity.
Fault Code 6: Parameter assignment error – the module has received incorrect or incomplete parameterization data from the controller
Review and correct the module parameters in STEP 7 or TIA Portal. Perform a new download to the interface module and restart the station.
Fault Code 7: Bus communication error – intermittent or persistent loss of communication between the interface module and the CPU
Inspect PROFIBUS cable shielding and connector integrity. Check for address conflicts, verify baud rate settings, and ensure proper bus termination at both ends.

Frequently Asked Questions

What electronic modules are compatible with the 6ES7193-4CB20-0AA0 terminal module?

The TM-E15S24-A1 terminal module is compatible with 2-wire and 4-wire electronic modules in the ET 200S range, including digital input, digital output, and analog modules. The specific electronic module must be selected according to the application requirements and inserted into this base terminal module.

Can the electronic module be replaced while the system is powered (hot-swap)?

Yes, the ET 200S terminal module design supports hot-swapping of electronic modules. The field wiring remains connected to the terminal module while the electronic module is removed and replaced, minimizing downtime.

Which engineering software is used to configure the ET 200S station containing this terminal module?

The ET 200S system is configured using Siemens STEP 7 (for classic S7-300/S7-400 systems) or TIA Portal (for S7-1200/S7-1500 and newer systems). The hardware configuration must include the correct terminal module and associated electronic module types.

What is the supply voltage for the 6ES7193-4CB20-0AA0?

The terminal module operates with a 24 V DC supply voltage, which is provided via the ET 200S power module mounted on the same rail.

What DIN rail size is required for mounting the ET 200S terminal modules?

ET 200S terminal modules, including the 6ES7193-4CB20-0AA0, are mounted on a standard 35 mm DIN rail (EN 60715).

Troubleshooting

Electronic module status LED shows red or fault indication after insertion

Check whether the inserted electronic module type matches the hardware configuration in STEP 7 or TIA Portal. Verify the module is fully seated on the terminal module.

Ensure the correct electronic module is inserted. If the module type has changed intentionally, update the hardware configuration and download to the interface module. Re-seat the module firmly until it clicks into place.

Field signals not detected despite correct wiring

Inspect the spring-loaded terminals on the terminal module for proper wire insertion. Measure signal voltage at the terminals with a multimeter to confirm field device output.

Re-insert field wires into the spring terminals ensuring the wire is fully inserted and the terminal is properly engaged. Replace the terminal module if terminal damage or contact failure is suspected.

ET 200S station not recognized on PROFIBUS or PROFINET after installing a new terminal module

Verify that the terminal module is correctly positioned on the DIN rail and that the bus connector between modules is properly engaged. Check for any gaps or misalignment in the module row.

Remove and re-seat all modules in the station to ensure the internal bus connectors are fully engaged. Confirm the station address and configuration match the engineering project settings.

Intermittent I/O faults reported by the CPU for channels on this terminal module

Check the field wiring for loose connections at the spring terminals. Inspect the electronic module for signs of overheating or physical damage. Verify the 24 V DC supply stability.

Re-terminate all field wires at the terminal module. Replace the electronic module if damage is found. Stabilize the 24 V DC supply and check for voltage drops under load.

Terminal module cannot be removed from the DIN rail

The ET 200S terminal modules are mechanically interlocked when the station is assembled. The locking mechanism must be released before individual modules can be removed.

Use a screwdriver to release the DIN rail locking tab on the bottom of the terminal module. Ensure adjacent modules are also unlocked if the entire station needs to be disassembled.
