go-iecp5 library for IEC 60870-5 based protocols in pure go. The current implementation contains code for IEC 60870-5-104 (protocool over TCP/IP) specifications.

asdu package:
clog package:
cs104 package:

Feature:

• client/server for CS 104 TCP/IP communication
• support for much application layer(except file object) message types,

总召唤确认报文

你好example中server_general例子中当主站发起总召
[68 0e 00 00 00 00 64 01 06 00 01 00 00 00 00 14]

从站回应的总召确认报文少了信息体地址00 00 00
[68 0b 00 00 02 00 64 01 07 00 01 00 14]

调试过程中发现此函数
func (sf *ASDU) DecodeInfoObjAddr() InfoObjAddr {
var ioa InfoObjAddr
switch sf.InfoObjAddrSize {
case 1:
ioa = InfoObjAddr(sf.infoObj[0])
sf.infoObj = sf.infoObj[1:]
case 2:
ioa = InfoObjAddr(sf.infoObj[0]) | (InfoObjAddr(sf.infoObj[1]) << 8)
sf.infoObj = sf.infoObj[2:]
case 3:
ioa = InfoObjAddr(sf.infoObj[0]) | (InfoObjAddr(sf.infoObj[1]) << 8) | (InfoObjAddr(sf.infoObj[2]) << 16)
sf.infoObj = sf.infoObj[3:]
default:
panic(ErrParam)
}
return ioa
}
会把asduPack中infoObj里的信息体地址去掉，导致sf.handler.InterrogationHandler(sf, asduPack, qoi)函数参数中asduPack里没有信息体地址？
是不是我哪里看的有问题 我看您这边说已经在工程中使用了 应该不会有这样的问题吧？谢谢！

Supporting IEC101

Will you support iec101?

What about implement synchronous Read and Write functions

Refusing connection

Hi @thinkgos Thank you for this project it is working great so far.

I am wondering if there is a way to refuse a connection from server.

I have a server and multiple clients, can I limit the connect to server?.

I have try to close "UnderlyingConn()" but clients keep trying connect with attempt.

Do you have any other idea, maybe sending an ASDU like StopDT from server?

使用示例

您好，请问有计划写一些详细点的server/client应用例子吗？
谢谢.

Joint Forces

Hi there. 👋 I made a Go implementation a while ago too. It's all open source. You're welcome to join.

https://github.com/pascaldekloe/part5

The code is near complete. The final version was lost on a company laptop by accident. If this is a commercial endeavour then I'd be happy to finish my project again for 11,000 Euro, delivered on January 2021. The final product includes a command line tool plus your issue #2, #8 and #10.

104服务端崩溃

使用客户端工具连接时会自动失联
存在服务端崩溃
好像没有校时
我再看看

about client example?

I want get some data from ice4 server,client is todo ?

读命令使用

想请教下read command的使用问题
使用场景：遥调（AO）读（66H）
问题：从站返回报文返回未知信息对象地址。这个是和什么有关？
调试：信息对象地址=点号+遥调偏移量。从站设置了不同的遥调偏移量0x6001 0x6101 还有其他任意设置偏移地址，都无法调通。

master-slave mode

Read data

How should the data be read, Any examples?

The "ReadCmd" func?

support client ??
