// 960222-960315  Ver 1.00  PGa @ StH”ga SWEMASS / INDEL AB
//  First version using PC CPU to run positioning of slat infeed
//  and the M2400 and M3410 modules.
// 960222 New orders: the machine has to be standalone operable, i.e.
//  it has to be programmed with the americans rules, but they are in the
//  same manner as the Europe std, only with inches instead.
// 960227 New orders: we must! use the new SMC pneumatic modules.
//  change drawings, outputs not on the M2400 modules anymore.
// 960304 New orders: we must! use the FOX10 and FOX20 modules instead.
//  change drawings, driver routines has to be modified.
// 960307 New orders: ALL functions and options as is on 622A-B has to
//  be included, deliverydate not changed.  Plus fixture changers as option
// 960313 New orders: The machines are not Europe std rules but all special
//  according to rules "bible" brought home by Bertil today.
//  Very special production with double blinds on one headrail included.
// 960318 New orders: The machine will now also include reading
//  (and controlling ?) the bow setting on the profiling unit.  When color
//  is changed this setting should also be adjusted accordingly.
//  New hardware design and new SW for machine.
// 960321 New: Server mode & communication will not be installed until
//  at least winter -96 (Bertil)
// 9604xx New: Valance production has to be included in machine and server
//  communication.
// 9604xx New: no, server-system must be delivered now! (Bertil).
//  Server software Is to be written by US!  If we would use the specs on
//  communication we've already made, then we have to have US rules in the
//  server SW.  Noone has time to write that; Scrap the specs.
//  We have to write simpler, special custom SW f the communication.
// 9604xx New: Normal editing for machines not sufficient.
//  Production data is divided into "normal - displayed in list" and
//  "special 'details' - displayed separately"
// 960429 New: Valance production has to be run by the OPERATOR.  Data from
//  server is only recommendation.
//  -new panel functions, separate production sequence for valance.
//  Bow trim has to be connected to slat color AND to slat GAUGE.
//  -new code for color and gauge combined into one.
// 960523 New: Endstop station logic DO has to be on these machine.
