SysIo, System I/O<br />
EXTENDED REGISTER GROUPS<br />
Writing here affects bit 4 <strong>of</strong> n <strong>of</strong><br />
the external RS422 transceiver properly. Writing to<br />
ot affect the etting!<br />
Getting into synchronization to the master after enabling slave<br />
synchronization may take several seconds. DMC nits that<br />
share resolvers must be synchronized and remain<br />
synchronized while the shared resolvers are used.<br />
A resolver is considered shared if a DMC 2 SysIo.POut to set the directio<br />
SysIo.POut does n SysIo.Sync s<br />
2<br />
u<br />
unit that is not<br />
driving the excitation for said resolver reads it.<br />
Synchronization must also take effect before the resolver<br />
RD1.SHAdj and RD2.SHAdj parameters<br />
are calibrated.<br />
If a slave wants to desynchronize, it must first set:<br />
SysIo.Sync = 0<br />
To become master, and then immediately turn OFF the<br />
synchronization-line driver by clear bit 4 in<br />
SysIo.POut = 0.<br />
(Write BCLR SysIo.POut, 16) to prevent<br />
jamming the<br />
synchronization-line for the other units.<br />
SysIo.MemStat 19 0..65536 RW<br />
Status <strong>of</strong> system memory. Support two blocks <strong>of</strong> EEProm (32<br />
bit values.)<br />
Bit0 (1)=1 EEprom activity completed. ( EELoad/EEStore done.)<br />
Bit1 (2)=1 Checksum error in firmware PROM.<br />
Bit2 (4)=1 Block0 (EEProm.0 – EEProm.63)<br />
Checksum error in configuration EEprom variables. (EEProm.0<br />
– EEProm.28) Set by the EELoad instruction. Must be cleared<br />
by the PL program as the EELoad instruction does not clear<br />
this bit.<br />
Bit3 (8)=1 Block0 (EEProm.0 – EEProm.63)<br />
Checksum error in user EEprom variables. (EEProm.30 –<br />
EEProm.62) Set by the EELoad instruction. Must be cleared by<br />
the PL program as the EELoad instruction does not clear this<br />
bit.<br />
Bit4 (16)<br />
EEprom size,<br />
0 = EEProm size is 1024 bit (93C46)<br />
1 = EEProm size is 4096 bit (93C66)<br />
If the EEProm size is 1024bit then only the lower<br />
64 EEProm registers will be saved.<br />
Bit5 (32)=1 Block1 (EEProm.64 – EEProm.126)<br />
Checksum error in configuration EEprom variables.<br />
(EEProm.64 – EEProm.92) See Bit2.<br />
Bit6 (64)=1 Block1 (EEProm.64 – EEProm.126)<br />
Checksum error in user EEProm variables. (EEProm.94 –<br />
EEProm.126) See Bit3<br />
Bit7 (128) 1 = EEProm size is 16384 bit (93C86)<br />
Bit8 (256) Reserved<br />
Bit9 (512) Reserved.<br />
