shows its kind+slot designation (`DI0`, `DO2`, `AI4`, …) in the
module header's upper right corner — same size and vertical
alignment as the article number — and the channel indicators carry
only the 0-based channel number: below each DI/DO LED, and on analog

mirroring the physical two-deck layout of 16-channel WAGO modules.

Underflow/overflow are indicated: the bar fills in the limit color
(red) and a small red LED above the bar lights for overflow, below
the bar for underflow, clearing when the value returns to range.
**Signed values** (2026-10-04): range bounds may be negative —
`-65534 <= min < max <= 65535` (the raw 16-bit image holds
0–65535; a negative display bound lets signed plant quantities map
onto the bar). Simulated AI values and AO forces accept negative
numbers within the same window; values are stored in the image
as their 16-bit two's-complement representation.
