20 Sercos transmission speed at 8 Mhz and 16 Mhz
Regardless of the baudrate used, always respect the values
recommended by g.mp. SERPOWSE (P121).
SERSPEED (P120) This g.m.p. sets the Sercos transmission speed in Mhz.
When using the SERCOS816 board, this parameter may also be
assigned the following values:
With the rest of the boards, the only values admitted are 2 and 4, like
until now. The other values will be considered as 4 Mhz except when
setting a value of 1, in that case it assumes a speed of 2 Mhz.
The type of board installed may be checked in diagnosis mode, in
hardware configuration. The new board will be identified as
"SERCOS816".
With previous software versions, the transmission speed of this board
will be limited to 4 Mhz.
21 New range of G functions
The range of available G functions has been increased to 319.
22 DNC communication status
DNCSTA It may be used to know from the PLC the status of the RS transmission
even when not having the DNC option.
This parameter has 16 bits that will count from left to right. There is
one bit for each DNC . The bit will be set to "1" when transmission is
in progress:
23 The motionless simulation ignores G4
The dwells set in a program through G4 K are ignored when simulating
without movement.
The G4 K blocks will not be executed when simulating the theoretical
path, the G functions or the G, M, S and T functions.
