FAQs:
  • What are the main operating modes of the IMMFP12 module?
    The IMMFP12 operates in three modes: execute mode for running control algorithms with self-diagnostics, configure mode for editing or creating control logic, and error mode which activates automatically when faults are detected during execution.
  • How does the redundant processing capability work?
    A 1 Mbaud CPU-to-CPU communication link allows a backup MFP module to maintain hot standby status. If the primary module fails, control transfers seamlessly to the backup in a smooth, bumpless switchover.
  • What programming languages and methods are supported?
    The module supports multiple programming options including C, BASIC, BATCH, ladder logic, function codes, and user-defined functions, enabling flexible implementation of complex control strategies.
  • How many I/O modules can the IMMFP12 communicate with?
    The MFP module is capable of communicating with up to 64 analog and digital I/O modules in any combination within the INFI 90 OPEN system.
