ABB 07KT93, identified here by order number GJR5251300R0171, is a central processing unit for Procontic CS31 installations. ABB’s programming reference explicitly includes the 07KT93 and maps its local binary inputs to E 62,00 through E 63,07 and its local binary outputs to A 62,00 through A 62,15. These correspond to 24 local input addresses and 16 local output addresses; the separate high-speed operands must be interpreted using the controller configuration.
For software integration, the reference identifies E 63,14 and E 63,15 as high-speed binary inputs with a stated delay of 0.02 ms. Counter content is read through EW 06,15, while AW 06,15 carries the counter start value. Clock values occupy EW 07,08 through EW 07,14, and EW 07,15 reports CS31 bus, clock and battery status. Program-cycle configuration uses KD 00,00 in integer multiples of 5 ms; this is a configured cycle-time requirement, not a guaranteed execution time for every application.
Replacement planning should preserve the executable program, symbols, system constants, field wiring schedule and the installed unit’s complete nameplate identification. An integrator should verify local and remote I/O addressing before a controlled return to service, while the MRO purchase specification should state GJR5251300R0171 and the required revision. The linked ABB programming document supports the operand data shown here; it does not establish a universal hardware interchangeability approval or the suitability of a differently suffixed 07KT93 safety variant.

Preserve the CS31 program, system constants and local/remote I/O map before replacement or migration.
The ABB reference lists E 62,00 through E 63,07 for the 07KT93 central unit: 16 addresses in group 62 and eight in group 63. A commissioning checklist that stops at E 62,15 omits the last eight local input addresses. Reconcile each operand with the approved terminal and signal schedule before testing.
No. It is the stated delay TD for high-speed binary inputs E 63,14 and E 63,15. Program scheduling, logic execution and the output or actuator path also affect the end-to-end response. Measure the complete chain under the actual application rather than promising a 0.02 ms machine reaction.
EW 06,15 reads the counter content and AW 06,15 specifies its start value. They are not interchangeable merely because the numeric address is similar. Confirm the intended starting state, counting logic and associated zero-crossing behavior before re-enabling the connected mechanism.
No. The published definition for KD 00,00 permits only integer multiples of 5 ms. Choose an allowed setting that also accommodates the actual program and required process timing, and validate it against the installed controller’s applicable software documentation.
Clock reading uses EW 07,08 through EW 07,14. EW 07,15 instead contains status for the CS31 system bus, clock and battery. Record these separately during fault investigation; interpreting the status word as another clock field can conceal the original diagnostic information.
Do not treat hardware supply as proof of software entitlement. ABB’s 907 PC 331 documentation includes separate software registration and licence material. An MRO buyer should establish access to the approved programming environment, project files and any required licence or registration independently of the spare CPU purchase.
The reference assigns system constants to operating mode, initialization behavior, COM 1 use, error response and CS31 initialization. Restoring only the application without the matching constants can change startup or communication behavior. Preserve the verified project package and compare its settings before controlled commissioning.
Do not approve that substitution from the shared model stem. A differently suffixed safety unit requires its own technical assessment, approved documentation and site authorization. Specify the exact GJR5251300R0171 identity on the purchase and receiving records, and escalate any offered variant before shipment.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
