CPU 102 and 103

eisenpferdreiter

it could work, as both CPUs are same family. Just be aware that CPU 102 has lower limits in many ways than CPU 103.
For example:
Markeraddreess from 0.o to 127.7 for CPU 102
Markeraddreess from 0.o to 255.7 for CPU 103
Counter 0 to 31 for CPU 102
Counter 0 to127 for CPU 103
Timer0 to 31 for CPU 102
Timer0 to 127 for CPU 103

if your program does not make full use of CPU103, especially from memory, it could work.
See here for technical details of CPUs S5-100U , unfortunatelly in German only.

Hello diosnel

Well. I would doubt that you would be able to use a CPU 102 in place of CPU 103 in most cases ( Unless of course that the CPU 103 was un-necessarily used where CPU 102 was sufficient )

Although the two belong to the same family as correctly pointed out by eisenpferdreiter, there are major differences besides thouse already pointed out :

Memory : CPU 102 : 2048 Statements , CPU 103 : 10240 Statements

Blocks( PBs / FBs, DBs) : CPU 102 : 0-63 , CPU 103 : 0-255
( CPU 102 does not support SBs )

No of Operations Supported : CPU 102 : 60 , CPU 103 : 180
( CPU 102 Does not support Supplementary operations and FBs with Formal Operands )

Attached pl find Technical specifications ( English ) of CPU 102 and CPU 103

Hope this helps
