"""B6 bench leg: IEC 60870-5-104 master client (GI + COV round-trip).
|
|
|
|
Task card: docs/任务规划/W1-采集保护收尾.md (B6 DoD); protocol baseline:
|
|
docs/子系统设计/IEC104上行设计说明.md §3/§4. Constants mirror
|
|
App/protocol/iec104/iec104_asdu.h / iec104_link.h.
|
|
|
|
Flow:
|
|
1. TCP connect device :2404, STARTDT act/con (enter RUN).
|
|
2. General interrogation C_IC_NA_1 (QOI=20): expect actcon, background
|
|
scan (YX double-point group SQ=1 -> YX single-point group SQ=1 ->
|
|
YC group SQ=1 -> frequency single point), actterm.
|
|
3. Deterministic COV trigger: bench analog inputs are floating (phasor
|
|
rms is 0..0.3 raw-code noise only; the standard source belongs to
|
|
B10), so we use the two-step C_SE_NC_1 write to temporarily lower
|
|
the OC1 current setting (comm addr 0x8858, default 10.0 A) to
|
|
0.05 A -> protectTask (20 ms cadence) asserts OC1 -> YX16/YX15
|
|
spontaneous (COT=3) uplink. This is exactly the "104 YX linkage"
|
|
leg left open by B5. Then restore 10.0 A -> YX16 returns.
|
|
4. YK11 (0x600A) two-step select/execute -> positive actcon (reset
|
|
request consumed asynchronously by protectTask, B5 contract).
|
|
5. C_RD read back 0x8858 ~= 10.0 (restore confirmation).
|
|
|
|
Exit codes: 0 = all checks PASS; 1 = any check FAIL; 2 = connect or
|
|
protocol error. Output is pure ASCII (redirect stdout to archive the
|
|
round-trip log as bench evidence).
|
|
|
|
Usage: python iec104_master.py [--ip 192.168.1.100] [--port 2404]

B7 bench leg modes (setpoint persistence + global soft plate, task card

--b7-pre : before reset: mark setpoint 7.5 (C_SE+C_RD), YK12 OFF (two-step)

|
-> low setpoint 0.05 must NOT trip YX16 (plate OUT disables

--b7-post: after reset: C_RD 10.0 (setpoint persisted); low setpoint 0.05
