Application-Specific FAQ
Q: Can the TSX3721101 communicate with SCADA systems via Modbus?
A: Yes. With the addition of a TSX SCM 2161 or compatible communication module, Modbus RTU/ASCII over RS-485 is supported natively.
Q: Is PL7 Pro software still available for programming?
A: PL7 Pro is available from Schneider Electric’s software portal. Konmask can advise on compatible cable and driver setup for modern Windows environments.
Q: What is the maximum number of I/O points this base can support with expansion?
A: The TSX Micro platform supports up to 3 extension modules, allowing up to ~104 discrete I/O points depending on module selection.
Q: Can this unit replace a TSX3710001 or TSX3720101?
A: The TSX3721101 is the 24 VDC transistor-output variant. Verify output type and supply voltage compatibility before substitution; program migration is generally straightforward within the TSX Micro family.
Q: Do you provide a warranty?
A: Yes. All units carry a 12-month warranty against manufacturing defects. Contact support@konmask.com for claims.
