This interface requirement is a guideline for those PLCs which need to be connected to the network and monitored. The detailed specifications will be defined during technical evaluation and detail design.2 本文档名称的概念/ Concept used in this document●PDU: PMC数据采集服务器PDU: PMC Production Data Unit (Data Collector Server)●Station：A location where work is performed●Cell：A gated area containing 1-32 Stations and controlled by 1 PLC●Alarm information：Alarm information means the alarm signals which will cause equipment orconveyor to stop.●Warning information：Warning information means the alarm signals which will not cause equipmentor conveyor to stop but need to maintain the equipment.●Starve：Starve means an area is idle because it is waiting for the parts from the preceding area along theproduction line.●Block：Block means an area is idle because the following area along the production line is not able toaccommodate any more parts from this area.●Andon Downtime：An alarm which produced by Andon fault●E-Stop Downtime：The emergency stops Time. Typically a button that you press to stop the machine inthe event of an emergency●Timer：A timer is a specialized type of clock. A timer can be used to clock some alarms.●Counter：A counter used to collect something number of times. Something like the Production.3 PMC数据采集器和车间现场PLC之间的通讯方式/ Communicationmode between PMC PDU and PLCs●通讯协议：TCP/IPCommunication Protocol: TCP/IP●网卡：PLC自带支持TCP/IP协议、带RJ45网络接口的网卡Network Adapter: OEM provide PLC network adapter which has RJ45 port and support TCP/IPprotocol●通讯速率：10/100MbsCommunication Speed: 10/100Mbs●IP地址：固定的IP地址IP address: Fixed IP address●数据采集方式：所有的Alarm以及Information信息由PMC使用Pull方式采集。

All Alarm and information will be collected by PMC using Pull mode.●计时、计数等其他信息由数据采集服务器采用PULL方式进行采集，数据采集频率由数据采集器定，扫描间隔不大于10秒Timer, Counter and other information will be collected by PMC Data Collector using Pull mode. Data collecting rate: decided by Data Collector, scan interval should less than 10 seconds4 PMC接口对OEM编程的要求/ OEM must obey these rules duringprogramming●所有这些High Alarm和Low Alarm信息要求按照Station分块存放；每一块中各类报警信息按各自优先级从高到低排列；All the High-Alarm information and Low-Alarm information should be stored respectively according to the Station. Each type of the information should be arranged according to the priority from high to low.●每个Cell最多可以设置32个StationThe maximum number of station is 32 for each Cell.●设备供应商应按照附录一的要求提供报警清单文件OEM should provide the alarm data file according to the appendix 1.5 PMC接口描述/ Interface description5.1 PMC 接口模块内存分配情况/ PMC interface memory allocationPMC 接口内存分为4个区域，如下：●PMC接口数据交换区●生产报警监控区●生产计数监控区●模拟量数据监控区PMC memory interface is divided into three regions, as follows：●Data Exchange Area●Produce Alarm Monitor Area●Produce Count Monitor Area●Analog data Monitor Area5.2 接口详细说明/ Detail Interface注意：标记有“OEM Write”的数据是OEM需要提供的数据，OEM需将相应的信息填入该区域(具体信息见《PMC接口模块内存分配情况.xls》)PMC系统接口模块内存分配V1.0.xlsNotes: The mark has “OEM Write” the data is the data that need to be supplied by OEM，OEM need to fill in all these area with correct data（For detail information see 《PMC Interface Memory MAP.xls》）.5.2.1 PMC接口数据交换区/ Data Exchange Area目前设计的PMC接口为每个PLC保留了最多32个Station，具体使用情况如下图：There are maximum 32 Stations reserved for each PLC. The detail information is as below:工位数量/ number of stations其中第一个Word用来存放Station的数目，如果为1，则只有接下来的Station1的数据，Station2~Station32的数据为空。

The first word is used to store number of stations. If the number is 1.Then the data of Station2 to Station32 is null and there is only data of station1.计时触发信号/ Timer Trigger Signal用于接收OEM提供的计时器的触发信号，这个Word是按位使用，其中每一位存放一个计时器的触发信号。

第一位（最低位）存放设备故障停线时间的触发信号；第二位存放缺料停线时间的触发信号；第三位存放堵塞停线时间的触发信号；第四位存放ANDON停线时间的触发信号；第五位存放生产停线时间的触发信号；第六位存放紧急停线时间的触发信号；第十六位存放所有故障停线时间的触发信号(即＝Machine Fault OR Stave OR Block OR Andon ORProduction-Stop OR Emergency–Stop)；Used to receive Timer trigger signal that OEM supplied. This Word is used by bit. Each bit stores the trigger signal of one calculagraph.The first Bit(Lowest Bit,Bit0)stores the trigger signal of Machine Fault Downtime.The second Bit(Bit 1) stores the trigger signal of Starve Downtime.The third Bit stores the trigger signal of Block Downtime.The fourth Bit stores the trigger signal of Andon Downtime.The fifth Bit stores the trigger signal of Production-Stop Downtime.The sixth Bit stores the trigger signal of Emergency–Stop DowntimeThe 16th Bit stores the trigger signal of All Fault Downtime. (=Machine Fault OR Stave OR Block OR Andon OR Production-Stop OR Emergency–Stop)控制字/ Control Register该控制字是PMC提供给OEM程序用来控制计数、计时器所用。
