Key Characteristics
Compact DCS for small-medium plants
FBD/LAD primary programming
File-based engineering (PRT, DMF, CSV)
BST_LIB (standard) + BST_USER (custom) function block libraries
MSR points as primary addressable entities
DigiVis for operator displays
DIGI protocol for internal communication
Motor Control: IDF_1 + MOT_T1 MOTOR1 Structure (11 signals):
IN: AC (auto cmd), PR0 (safety), MA (req auto), MM (req manual)
OUT: ILK (interlock), RDY (ready), RUN (running), LOC (local), AUT (auto), FLR (fault), SDS (shutdown)
Automation Approach
PRT file templating (text replacement)
CSV project parsing/generation
No public API (file manipulation is the standard approach)
Checksum can be set to 0; Freelance recalculates on import

Motor Control: MotL Block (APL) Inputs: ModLiOp, AutModOp, ManModOp, FbkRun, Protect, Intlock01, CmdStrt, CmdStop, MonTiRun, MonTiStp
Outputs: ModLiOp_Out, StartOut, RunOut, StopOut, Trip, SwiToLoc

Automation: TIA Portal Openness API (.NET) using Siemens.Engineering;
TiaPortal tia = new TiaPortal(TiaPortalMode.WithUserInterface);
Project project = tia.Projects.Open(new FileInfo(@"Project.ap17"));
PlcSoftware sw = device.GetService<PlcSoftware>();
sw.BlockGroup.Blocks.Import(new FileInfo(@"Block.xml"), ImportOptions.Override);
Capabilities: create projects, import/export blocks as XML, create tags, generate HMI screens, compile, download.
HMI: SiVArc Rules-based auto-generation: "For every MotL instance, create a faceplate." Reads PLC structure, generates WinCC elements.

Node Connect Diagnose OpenClaw node connection and pairing failures for Android, iOS, and macOS companion apps. Use when QR/setup code/manual connect fails, local Wi-Fi works but VPS/tailnet does not, or errors mention pairing required, unauthorized, bootstrap token invalid or expired, gateway.bind, gateway.remote.url, Tailscale, or plugins.entries.device-pair.config.publicUrl.
