Processing and Memory Capacity Model

The processing capability of the C300 controller is measured in "Execution Unit" (XU) units. C300 50ms CEE provides 5500 XU for user control, I/O, and communication purposes; C300 20ms CEE provides 5000 XU, but various operations in high-speed CEE contribute additional XU weights.

I/O Capacity and IO UNIT Definition

The I/O capacity of the C300 controller is measured in units of "IO UNIT" (IOU), and different I/O devices consume different quantities of IOUs.

IO device or module IO UNIT consumption

1 PM IOP module 1

1 Series C I/O module 2

1 serial interface module (SIM) 6 (C300)

1 pulse input module (PIM) 1.5

1 Series C FIM4 4

1 Series C FIM8 8

1 non redundant FIM2 2

1 redundant FIM2 paired with 2

1 DHRIO module 0

1 SST-PFB-CLX Profibus module 4.5

1 DeviceNet Bridge Module (DNB) 4

Capacity limit:

The maximum IOU count for C300 50ms CEE is 64 (any combination), which can be extended to 80 if using only PM IOP or Series C IOM

The maximum IOU count for C300 20ms CEE is 12

The maximum number of IOUs per I/O link is 40 (50ms)/6 (20ms)
