ICS TRIPLEX 9801工控模块系统备件
实时时钟必须输入正确的时间和日期，事件记录器事件才能正确标记时间/日期。电池支持的内部时钟即使在断电的情况下也会持续运行。它的精度大约为每月±1分钟。必须通过前面板或RS485串行链路时钟更新命令定期手动纠正。如果没有与其他继电器同步的事件发生的大致时间足够，则前面板键输入时间/日期就足够了。如果使用RS485串行通信链路，则所有继电器可以保持同步时间。远程计算机通过RS485端口将新的时钟时间预加载到469存储器中，以连接到通信信道上的每个继电器。在计算机广播（地址0）“设置时钟”命令后，系统中的所有继电器在同一时刻开始计时。在接收串行命令时可能有长达100 ms的延迟，因此每个继电器的时钟时间为±100 ms，±PLC或PC的绝对时钟精度。有关时间预加载和同步命令编程的信息，请参阅第6章：通信。n串行端口n[ENTER]获取更多从属地址：254范围显示默认消息。可以选择1到20条默认消息。多个默认消息以S1 469 SETUP×PREFERENCES默认消息周期时间设置点确定的速率自动按顺序扫描。可以选择任何实际值进行默认显示；此外，最多可以创建和显示五条用户可编程消息（消息草稿）。例如，继电器可以交替扫描电机识别信息、各相电流和最热定子RTD。默认消息显示在S1 469 SETUP（设置）×Default messages（默认消息）子组中。使用以下步骤添加默认消息：1。为S1 469 SETUP（设置）passcode（密码）Enter passcode for ACCESS（进入密码）设定点输入正确的密码（除非密码已输入或密码为“0”，否则会破坏密码安全功能）。2.使用和键移动到要添加到默认消息列表的消息。所选消息可以是任何实际值或消息草稿消息。3.按下。消息PRESS[ENTER]TO ADD DEFAULT MESSAGES（按下[ENTER]TO添加默认消息）将显示5秒。4.在显示时再次按下可将当前消息添加到默认消息列表中。5.如果正确遵循程序，将显示以下闪烁信息：
Õ× REAL TIME CLOCK The correct time and date must be entered for event recorder events to be correctly time/date stamped. A battery backed internal clock runs continuously even when power is off. It has an accuracy of approximately ±1 minute per month. It must be periodically corrected manually through the front panel or via the RS485 serial link clock update command. If the approximate time an event occurred without synchronization to other relays is sufficient, then entry of time/date from the front panel keys is adequate. If the RS485 serial communication link is used, then all the relays can keep synchronized time. A new clock time is preloaded into the 469 memory via the RS485 port by a remote computer to each relay connected on the communications channel. After the computer broadcasts (address 0) a "set clock" command, all relays in the system begin timing at the same instant. There can be up to 100 ms of delay in receiving serial commands so the clock time in each relay is ±100 ms, ± the absolute clock accuracy in the PLC or PC. See Chapter 6: COMMUNICATIONS for information on programming the time preload and synchronizing commands. n SERIAL PORTS n [ENTER] for more SLAVE ADDRESS: 254 Range splays default messages. Between 1 and 20 default messages can be selected. Multiple default messages automatically scan in sequence at a rate determined by the S1 469 SETUP Õ× PREFERENCES Õ DEFAULT MESSAGE CYCLE TIME setpoint. Any actual value can be selected for default display; in addition, up to five user programmable messages can be created and displayed (Message Scratchpad). For example, the relay can alternately scan a motor identification message, the current in each phase, and the hottest stator RTD. Default messages are shown in the S1 469 SETUP Õ× DEFAULT MESSAGES subgroup. Use the following procedure to add default messages: 1. Enter the correct passcode for the S1 469 SETUP Õ PASSCODE Õ ENTER PASSCODE FOR ACCESS setpoint (unless the passcode has already been entered or the passcode is “0”, defeating the passcode security feature). 2. Move to the message to be added to the default message list using the and keys. The selected message can be any actual value or Message Scratchpad message. 3. Press . The message PRESS [ENTER] TO ADD DEFAULT MESSAGES will be displayed for 5 seconds. 4. Press again while displayed to add the current message to the default message list. 5. If the procedure was followed correctly, the following flash message will be displayed:
