IP 266 STEP 5 Programming

9.4.4 Selecting Modes via IB 4

All modes are selected in FB 26. In almost all cases, the number of the FB is iden-

tical to the mode number.

• FB 2 is for "Jog 2" mode

• FB 5 is for approach/set reference point mode

• FBs 6, 8 and 9 are for modes 6, 8 and 9

• The only exception is mode 99. Since not all CPUs allow FB numbers as high as

99, the FB number for this mode is 10. This mode is also the only mode that is

directly invoked in OB 1.

All FBs for selecting a mode have the same structure. First, the number of the

mode, in binary, is entered in output byte 64 (output byte 64 is byte 0 of the

output frame; see Section 7.1). For some modes, the mode parameters are also

preset in dependence on specific conditions, and entered in the relevant bytes.

FB 10: Synchronize IP 266

FB 10 is always invoked automatically in OB 1 when bit 0 in byte 2 of the input

frame is "0" (IB 66).

If the IP has not been synchronized, mode 99 must be started with the TOGGLE

bit = "1" and the START function.
