手册中指出FB250好像是指模拟数据采集块。我看到有些项目图纸中一个模拟量模块有八路通道,由PW128至PW142。1、FB250里头的BG模块通道指什么?2、FB250里头的KNKT里头的KN通道号指什么?答:1、S5中的FB250和FB251是模拟量输入输出测量模块,对于与S7的FC105\FC106.例如:Name :RLG:AEBG : KF +128KNKT : KY 0,4OGR : KF +518 UGR : KF +0EINZ : F 0.2XA : DW 51FB : F 250.2BU : F 250.3TBIT : F 253.1 OGR: Upper limit of the output as a Integer (KF),即在这里定义上限值。UGR: Lower limit of the output as a Integer (KF),即在这里定义下限值。2、实例:FB250 is clearly described with a example. BG: place behind the CPU103, starting with 0 for the first card (KF = Integer value)KNKT: Channel number = x (0..3, start counting with channel 0) Channel type=y, 3..6 whereby the number gives the type of working (KY are two bytes)[1] [2] 下一页
