EZ600-DS04文本显示器是可编程控制器用的通用操作显示面板。通过它可以对PLC 内部的继电器和数据寄存器进行监视、设定和报警显示，同时也支持和单片机的通讯。
EZ600-DS04 通讯口可用来下载画面和系统文件，也可用作和PLC 通讯。目前EZ600-DS04文本显示器支持的PLC 类型有爱默生EC10 系列、爱默生EC20 系列、爱默生EC20H 系列、爱默生ETC 系列、三菱FX 系列、西门子S7-200 系列等。 Modbus 协议是应用于控制器上的一种通用语言。通过此协议，控制器相互之间、控制器经由网络和其它设备之间可以通信。它已经成为一通用工业标准。本规范主要描述了modbus 协议在GCM 中的实现。通讯采用应答方式，由主机发起请求，从机执行请求并且应答。GCM 作为从机通过地址设置加以区分， GCM 系列PLC 自己组网时，最多允许30个从站，并且从机可设置地址范围为1~31。GCM 系列PLC 作为主站与其他设备（做从站）组网，没有地址范围限制，但也最多允许30 个从站。GCM 系列PLC 支持广播方式，广播地址为00。
