The "SBC format" changed on Saia PCD® COSinus CPU's

FAQ #101048

 

Due to technical reasons the "SBC format" changed for the new NT CPU's (PCD3, PCD2.M487 and PCD2.M5xx7).

For the 10 Bit analogue modules like the W200 series the format changes as shown in the table below:

	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
"old" xx7 CPUs	MSB	*	*	*	*	*	*	*	*	LSB	0	0	0	0	0	0
SBC NT xx7 CPUs	0	0	0	0	0	0	MSB	*	*	*	*	*	*	*	*	LSB

* = Value

If the values should be converted from new Saia PCD® COSinus format to the old format, the following instructions can be used:

L       PEW  10     //10-Bit Saia PCD® COSinus SBC-Format
SLW  6
T      MW    10    //old 10-Bit SBC-Format

For the 12 Bit analogue modules likeW100, W3x0, W500 series the format changes as shown in the table below:

	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0
"old" xx7 CPU	MSB	*	*	*	*	*	*	*	*	*	*	LSB	0	0	0	0
SBC NT xx7 CPU	0	0	0	0	MSB	*	*	*	*	*	*	*	*	*	*	LSB

*= Value

If the values should be converted from new Saia PCD® COSinus format to the old format, the following instructions can be used:

L       PEW   70    //12-Bit SBC-NT SBC-Format
SLW  4
T      MW     70    //old 12-Bit SBC-Format
