.
Example 1 to 3 can be operated with screening times < 8ms. In ex-
ample 4, a screening time of 8 ms at least is required.
Example 1
D 4 axes
D 1 SR-CAN module
D 2 DESI65-K-CAN digital output modules with 1 byte each (1 O-Block/
module)
D 3 DESI65-K_CAN digital input modules with 1 byte each (1 I-Block/
module)
CAN-Bus 1 (X51) CAN-Bus 2 (X52)
4 axes all digital I/O-modules + SR CAN-modules
Number of O-blocks = 1 + 4 (axes) = 5 Number of O-blocks = 1 + 2 (Digital output blocks) =3
Number of I-blocks = 4 (axes) =4 Number of I-blocks = 3 (Digital input blocks) =3
Example 2
D 4 axes
D 2 DESI65-K-CAN digital output-modules with 1 byte each (1 O-Block/
module)
D 3 DESI65-K_CAN digital input -modules with 1 byte each (1 I-Block/
module)
D Coupling to another rho4
CAN-Bus 1 (X51) CAN-Bus 2 (X52)
4 axes + all digital I/O modules Coupling to the second rho4 control
Number of O-
blocks =
1 + 4 (axes) + 2 (Digital output blocks) = 7
Number of I-
blocks =
4 (axes) + 3 (Digital input blocks) =7
Example 3
D 5 kinematics with 4 axes each = 16 axes
D 2 B~IO-modules with 2 bytes digital outputs each (1 O-Block/module)
and 2 bytes digital inputs each (1 I-Block/module)
CAN-Bus 1 (X51) CAN-Bus 2 (X52)
10 axes 6 axes + 2 B~IO-modules
Number of O-blocks = 1 + 10 (axes) = 11 No. of O-blocks = 1 + 6 (axes) + 2 (Digital output blocks) =9
Number of I-blocks = 10 (axes) =10 No. of I-blocks = 6 (axes) + 2 (Digital input blocks) =8
