INFI90FCLib for AC 800M. INFI90FCLib is an AC 800M evolutionary library that
contains INFI 90 Function Codes. The purpose of the INFI 90 Function Block library
is to allow Harmony system owners to protect the intellectual property embedded
within their existing controllers. Specifically, the library is designed to make
evolution of Harmony control applications to AC 800M straightforward and simple.
The INFI90FCLib does this by providing an equivalent function block in AC 800M for
the function codes from Harmony. Table 3 lists the IEC 61131-3 Function Block Types
(FBTs) provided in the INFI90FCLib.

S800 I/O – Harmony Termination Unit (TU) prefabricated cables. To minimize
the risk and costs of re-terminating field wires, ABB has created a family of cables
that preserves the investments made in standard Harmony field wiring terminations.
These prefabricated cables allow for the I/O module upgrade to S800 I/O without
ever touching the field wires. The cables are used in place of the traditional NKTU
cables. They connect the existing TU to S800 I/O modules via standard cable plug-ins.
S800 I/O cables exist for 24 VDC Digital I/O, 4-20 mADC Analog I/O, TC, mV, RTD I/O
(ASM01, ASM02, and ASM03) termination units. Similar solutions exist for Harmony
Block bases (AIN, AOT, DIN, and DOT).
Whether replacing aging PLCs or incrementally upgrading older Network 90 / INFI 90
based controllers, especially AMM, LMM, COM, and MFC modules, these control evolution
products allow for seamless evolution to AC 800M – S800 I/O without the costs and risks
associated with “rip-and-replace” controller upgrade methods (summarized in Table 5).

Results in:
• Minimal loss of production
• Minimal risk
• Lower project costs
Table 5. By avoiding high project costs and production risks, ABB control evolution upgrades
cost 60 – 80% less than “rip-and-replace” alternatives
System 800xA’s Device Management features (Figure 23) lower lifecycle costs through
significant savings in the design, implementation, and operation of field equipment.
The harnessing of untapped potential from the substantial installed base of HART®
devices conforms with the ARC Advisory Group analysis that: “Users can employ many
of their HART field devices with new generation automation architectures, making the
migration to a new process automation system more economical while increasing the
availability of intelligent data that has long been under utilized.”
