pierre73 Posts: 3 Rating: (0)	Bonjour, j'utilise des cpu226 en modbus (rs485) pour la gestion demachine avec comme plateforme le programme tip41 depuis 2000, j'ai besoin d'utiliser une cpu222 car la cpu226 est trop puissance, pour la micro application que je doit réaliser prochainement. les zones mémoires des 2 cpu sont différentes, donc je ne peux pas utiliser directement le programme en place dans la cpu226 . est-il possible de m'aider à modifiercette partie de programme car je n'y arrive pas ? type: rs485 / sans parite / 1 bit stop / 9600baud / 8b merci d'avance pour votre aide

I need to use a cpu222 because the cpu226 is too much power, the micro application I must realize soon. 2 cpu memory regions are different, so I can't use the program in place in the cpu226 directly. is it possible to help me change this part of program because Ican not? type: rs485 / without parity / 1 stop bit / 9600baud / 8B Thanks in advance for your help Translation of the french version.

Greg_E Posts: 88 Rating: (2)	Hi pierre, sorry to tell but you have to change the V memory range and change all the adressing in cpu 222 the range are 0-2048 you have to match your 226 V memory to this 222 range and to hope there are enough memory, and to put there the modbus slave(if its what you desire) subroutines from library instruction and also set adressing range for modbus too from library properties. but first of all try to change the CPU adressing if its possible, as i saw most of registers are starts from 3000. Good luck, Best Regards, Greg.
