HEIDENHAIN iTNC 530 HSCI - Fast PLC Inputs

276 HEIDENHAIN Technical Manual iTNC 530 HSCI
Please note that a system with functional safety (FS) permits up to 256 safe,
dual-channel inputs (channels A and B). An MB 6xx FS from HEIDENHAIN
requires 56 of the safe inputs, and connector X9 of a system PL requires eight
additional safe inputs. This means that max. 192 safe inputs can be distributed
to the PLD-H xx-xx-xx FS.
The designation "Channel A" or ".A" for the PLC inputs is relevant only for I/O
modules with functional safety (FS).
Fast PLC inputs Only the first four slots of a PL 6xxx can be used for fast PLC inputs. The fifth
slot and the successive slots (on PL 6x06, PL 6x08) must not be defined as
fast PLC inputs.
The configuration of fast PLC inputs in the HSCI system corresponds to the
previous configuration using machine parameters.
