IRT and IR question

hello,

as you know, when there is a D445 and a CU320,we can use IRT comunicatio between.

ok,for example,axises A,B,C,D assign on D445,and axises E,F,G assign on CU320.

now,if A axis is the master axis,and the B,C,D,E,F,G are synchronous axis, so at this condiion,the CU320 and the D445 have to use IRT?

if ,there is no synchronization,is that means that i can use IR comunication?

thank you for you reply!

Hello,

Axis only available on a SIMOTION PLC not on a SINAMICS !

What is IR Communication?

i am sorry ,i mean RT,not IR.

for the first problem,i think i need to explain again.

there are 8 axises. 4 assign on the CU320 Intergret on D445,and the others are assigned on the external CU320.

Hi,

If you use a Telegram whith DSC (5ff or 105ff) then you must use IRT.

you mean if i use 105 telegram to control the axis then i have to use IRT?

thank you very much ,but can i know the theory or why?
