描述

该子程序将系统数字IO与EtherCAT从站IO相关联。
这允许用户使用以下语法处理从站的数字IO:
?Sys.din[<first system digital input bit>][<Range>]
Sys.dout[<first system digital output bit>][<Range>] = <value>

IMPORTANT.svgIMPORTANT

由用户仔细分配系统IO，并确保没有映射相同的系统IO 到多个IO（运动驱动器或IO模块）。

如果此规则被破坏，行为是未定义的 !!!
IMPORTANT.svgIMPORTANT
在启动EtherCAT主站之前，必须调用此子程序。参考EtherCAT General Guide和Setup EtherCAT获得更多信息


输出

从站地址，PDO索引，PDO子索引，第一个SYSTEM数字输出。
range - 数字IO的数量映射到相关的PDO。
inherent_offset - 在一些从站，如STX CDHD，PDO的大小为32位，但DIO映射为16到32，因此固有偏移量为16.

输出

None

返回值

None

声明

public sub EC_ASSOCIATE_PDO_TO_SYS_DIO(byval slaveAddr as long, byval PDOindex as long, byval PDOsubindex as long, byval systemDIOnumber as long, byval range as long, byval inherent_offset as long)

格式

call EC_ASSOCIATE_PDO_TO_SYS_DIO(<Slave address>, <PDO index>, <PDOS sub-index>, <first SYSTEM digital output>, <range>, <inherent offset>)

例子

call EC_ASSOCIATE_PDO_TO_SYS_DIO(drive_addr, 0x60FD, 0x0, drive_addr*100, 11, 16) ' 16 - 0x60FD对数字输入的固有偏移
call EC_ASSOCIATE_PDO_TO_SYS_DIO(drive_addr, 0x60FE, 0x1, drive_addr*100, 6, 16) ' 16 - 0x60FE对数字输出的固有偏移
如果 drive_addr == 3, 最后一个例子将驱动器的第一个数字输出映射到系统数字输出位300,
驱动器的第二个数字输出到系统数字输出位301，依此类推，直到Drive Dout 11和System DOut 311。
