Tricon控制器、Modbus主机、外部设备和控制程序可使用TR_SCAN_STATUS功能块读取钥匙开关的位置。钥匙开关的位置启用或禁用整个Tricon系统的功能，包括扩展和RXM底盘。此表描述了钥匙开关位置的含义。警告如果电池更换不正确，则有爆炸危险。只能使用制造商推荐的相同或等效类型进行更换。按照制造商的说明处理用过的电池。钥匙开关位置功能运行正常操作，具有只读功能。主处理器执行先前加载的控制程序，试图通过TriStation、Modbus主机或外部主机修改程序变量。然而，控制程序可以调用门控访问功能，以在指定的时间窗口期间启用外部主机写入。有关更多信息，请参阅正在使用的TriStation版本的库参考中的GATDIS和GATENB功能块。PROGRAM用于控制程序加载和验证。允许从TriStation软件控制Tricon控制器，包括下载全部和下载更改。还允许Modbus主机和外部主机写入程序变量。STOP停止读取输入，强制非保留数字和模拟输出为0，并停止控制程序。（保持输出恢复到钥匙开关转到停止之前的值。）建议安装和维修工艺相关设备时使用停止设置，但Tricon控制器的维修不需要使用停止设置。当钥匙开关转到停止位置时，您可以使用TriStation防止应用程序停止。注意，这是TriStation可以覆盖的唯一位置。有关更多信息，请参阅TriStation开发者指南中的“限制访问Tricon控制器”。远程允许通过TriStation、Modbus主机和外部设备写入控制程序变量。（不允许TriStation进行全部下载和下载更改。）扩展机箱29 Tricon v9–v10系统扩展机箱规划和安装指南本节包含有关8111型扩展机箱和8121型低密度扩展机箱的信息。8111型扩展机箱8111型Tricon扩展机箱允许在系统中包含额外的I/O和通信模块。8111型扩展机箱包括两个电源模块和八个用于I/O和通信模块的逻辑插槽。（通信模块只能包含在扩展机箱2中。）当系统从主机箱到扩展机箱的I/O总线电缆总长度不超过100英尺（30米）时，可以使用扩展机箱。图9典型型号8111扩展机箱C D E F G H I J K L M N O P Q R A B A、B冗余电源模块C、D相邻插槽中的Tricon通信模块E、F带热备用的数字输入模块G、H带热备用I的数字输入模块、J带热备用K的数字输出模块、L带热备用M的数字输出模块、，P热备用模拟输入模块Q，R热备用模拟输出模块RXM机箱31 Tricon v9–v10系统RXM机箱的规划和安装指南Tricon RXM机箱（型号8112）允许在距离主机箱超过100英尺（30米）的系统中包含额外的I/O模块。RXM机箱包括两个电源模块、一个主RXM或远程RXM集以及六个I/O模块逻辑插槽。最多可将3个主RXM机箱连接到主机箱。每个主RXM机箱最多可支持3个远程或扩展机箱，系统中总共支持9个远程RXM或扩展机箱。有关安装信息，请参阅第206页的安装RXM机箱。图11典型RXM底盘A B A、B C、D、E F G、H I、J K、L M、N O、P Q，R冗余电源模块一组3个模块，用于主RXM机箱通信插槽（空白）数字输入模块，带有热备用数字输出模块，带有带热备用通道故障报警的热备用模拟输入模块，带热备用数字输出模块对于电气额定值注：上述模块仅为示例。有关可用模块，请参阅第3章。120 VAC/DC$ĭ+]：，5（$：，5（120 VAC/DC$ĭ+）：，5
The position of the keyswitch is readable by the Tricon controller, Modbus masters, external devices, and the control program by using the TR_SCAN_STATUS function block. The position of the keyswitch enables or disable functions for the entire Tricon system, including Expansion and RXM Chassis. This table describes the meaning of the keyswitch positions. WARNING There is a danger of explosion if a battery is replaced incorrectly. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions. Keyswitch Position Function RUN Normal operation with read-only capability. The Main Processors execute the previously-loaded control program—attempts to modify program variables by TriStation, Modbus masters or external hosts are rejected. However, a control program may call gated access functions to enable external host writes during a designated window of time. For more information, see the GATDIS and GATENB function blocks in the Library Reference for the version of TriStation being used. PROGRAM For control program loading and verification. Allows control of the Tricon controller from the TriStation software, including Download All and Download Change. Also allows writes to program variables by Modbus masters and external hosts. STOP Stops reading inputs, forces non-retentive digital and analog outputs to 0, and halts the control program. (Retentive outputs return to the value they had before the keyswitch was turned to Stop.) The Stop setting is recommended for installation and service of process-related equipment, but is not required for service of the Tricon controller. You can use TriStation to prevent the application from halting when the keyswitch is turned to Stop. Note that this is the only position that can be overridden by TriStation. For more information, see “Restricting Access to a Tricon Controller” in the TriStation Developer’s Guide. REMOTE Allows writes to control program variables by TriStation, Modbus masters and external devices. (Download All and Download Change by TriStation are not allowed.) Expansion Chassis 29 Planning and Installation Guide for Tricon v9–v10 Systems Expansion Chassis This section contains information about the Model 8111 Expansion Chassis and the Model 8121 Low Density Expansion Chassis. Model 8111 Expansion Chassis The Model 8111 Tricon Expansion Chassis allows additional I/O and communication modules to be included in a system. The Model 8111 Expansion Chassis includes two Power Modules and eight logical slots for I/O and communication modules. (Communication modules can only be included in Expansion Chassis 2.) Expansion Chassis can be used when the total I/O Bus cable length for the system from the Main Chassis to the Expansion Chassis is not greater than 100 feet (30 meters).

RXM Chassis include two Power Modules, one Primary or Remote RXM Set, and six logical slots for I/O modules. A maximum of 3 primary RXM Chassis can be connected to the Main Chassis. Each primary RXM Chassis can support a maximum of 3 remote or Expansion Chassis, for a total of 9 remote RXM or Expansion Chassis in the system. For installation information, see Installing an RXM Chassis on page 206.

The I/O ports are grouped as three pairs forming a triplicated extension of the Tricon controller I/O bus. The communication speed is 375 kilobits per second, which is the same rate as for the internal Tricon controller I/O bus. This means the three control channels are physically and logically extended to the Expansion Chassis without sacrificing performance. This figure shows the location of the I/O Bus Ports, which includes a port for each input and output channel.

Power Modules convert line power to DC power appropriate for all Tricon modules. Any combination of Power Module models can be used in Tricon systems. For more
