| Parameter | Value |
|---|---|
| Width | 35 mm |
| Height | 147 mm |
| Depth | 129 mm |
| Weight (approx.) | 405 g |
Width 35 mm leaves room for up to 4 additional communication modules (CMs/CPs) in the right-side expansion slot. The hardware clock is battery-backed; replace the backup cell before the first maintenance cycle. ERROR and MAINT LEDs visible from the front panel; no separate power supply needed — draws from the backplane bus via the CPU slot.
Yes. It supports FBD and LAD with failsafe extensions, plus PROFIsafe for safety communication.
Yes. It supports MRP as redundancy manager or client (up to 50 devices in ring), and MRPD when IRT is active.
32 kbytes each for inputs and outputs, all in the process image.
Yes. Same 35 mm width, 147 mm height, 129 mm depth. Same connectors and DIN rail mounting. No rewiring needed for a panel originally built for the standard CPU.
