以前时间继电器都是S5T#格式的，现在需要再触摸屏上输入单位S的时间数，不想自己编辑个处理块，想问下，有没有现成的FC或FB块，能有自动格式转化功能的？
答：从上位机写整型数INT或实数REAL到PLC，首先该数值需包含以毫秒为单位的时间值，在写入PLC的数据存储区后，利用ITD（Integer to Double Integer）或RND（Real to Double Integer with Rounding Off）将该值转换为双整形，然后将该值写到类型为TIME的变量里，在程序中调用FC40，将TIME转换成S5TIME即可。
由HMI输入秒数，在PLC中进行换算：
秒数*1000 >>得到毫秒数 >> FC40(TIM_S5TI) >> 转换得到正确地S5TIME
1 前言
当今社会处于信息时代，由于计算机技术尤其是网络技术的发展，信息高速公路已经将世界紧密的联系在一起，在这种形势下，利用信息技术将单机的计算机应用扩展为局域网内的计算机应用，进一步扩展为远程世界范围内的计算机广域网控制系统，利用网络数据库进行信息的实时更新和跟踪共享，已经成为当前【地球村】环境下工业控制发展的必然趋势。
随着工业自动化的要求不断地提高，工业控制网络需要一种高速廉价、实时性和开发性好、稳定性和准确性高的网络，而以太网正具备上述所有的优势特点，随着它进入工业控制领域，工业自动化系统向着分布化、智能化发展的方向更进一步，可以肯定，基于以太网技术的工业控制网络将成为未来工业控制系统的发展方向，并将越来越广泛应用在现代化自动系统的各个领域。
本文基于台达的自动化产品，提出了一种以D-LINK路由器、ADSL-MODEM及3G上网卡为基本配置，配合DVP28SV+DVPEN01-SLL实现PC与PLC之间的以太网远程通讯方案。对于同行的工业控制远程通信应用，具备非常重要的应用价值，值得行业借鉴。
2 系统框架
系统框架如图1所示。
图1 系统框架示意图
系统采用DVP28SV主机+DVPEN01-SL台达PLC以太网通信模块，与D-LINK路由器、ADSL-MODEM依次连接到**电信网络服务商的服务器上，再通过上位PC机（通过3G上网卡连接）在网络上的操作实现广域以太网的远程通信。
3 系统设置
3.1 ADSL-MODEM配置
安装ADSL-MODEM，向电信部门申请宽带业务，索取上网账号和密码。保证PC1可直接通过ADSL-MODEM上的以太网口拨号登录互联网。
