Application-Specific FAQ
Q: Is the 1753-L32BBBM-8A compatible with Studio 5000 Logix Designer?
A: The GuardPLC 1800 series uses RSLogix Guard PLUS! as its native programming environment. Integration with Studio 5000 is achieved via EtherNet/IP messaging for supervisory data exchange, not direct programming.
Q: Can this controller achieve SIL 3 in a single-channel configuration?
A: No. SIL 3 requires a 1oo2D (1-out-of-2 with diagnostics) or 2oo3 voting architecture. Consult your functional safety engineer for the appropriate system architecture.
Q: What is the proof-test interval for this module?
A: Rockwell Automation specifies a maximum proof-test interval of 10 years for SIL 3 applications. Refer to the 1753-UM001 User Manual for full PFD/PFH data.
Q: Is this module still in production?
A: The GuardPLC 1800 series has reached end-of-life (EOL) status. Konmask.com specialises in sourcing verified surplus and refurbished units to support existing installations and brownfield projects.
Q: Do you provide a warranty?
A: Yes. All units carry a minimum 90-day functional warranty. Extended warranty options are available — contact us for details.
