該模塊監(jiān)控過載條件的輸出，并檢查開關(guān)的實際狀態(tài)與指令狀態(tài)相反。萬一過載或開關(guān)狀態(tài)錯誤，塊報告：開關(guān)故障。短路/過電流保護：診斷保護單個輸出電路防止過電流。對于源塊，加載通常會對電源的直流側(cè)短路。用于水槽塊時，負載通常對直流+側(cè)短路。如果指令輸出接通，且電流超過5安培持續(xù)1毫秒，電路自動關(guān)閉，故障開關(guān)消息已發(fā)出。
HIER466665R0099處理模塊必須通過將電源循環(huán)至阻塞，或通過從手持設備發(fā)送清除故障命令監(jiān)視器或總線控制器。浪涌電流：源塊和匯塊均處理穩(wěn)態(tài)正常運行期間的負載為0.5安培。浪涌電流保護確定在0.5安培之間安全切換負載的條件。首先，該塊必須配置手持式監(jiān)視器，以：輸入其設備編號（串行總線地址）。輸入其參考號（僅IC600和IC550需要）僅適用于系列PLC）。此外，除非塊上的所有電路都是輸入，否則塊I/O類型必須設置為程序塊上的輸出或組合ID屏幕。注意：如果塊脫機配置，則必須正確接地并在其串行1和串行2之間安裝一個75歐姆的電阻器終端。其余功能可以使用手持式監(jiān)視器，或通過從主持人。和4安培。下表顯示了允許的浪涌瞬態(tài)。
The block monitors outputs for overload conditions, and checks the
actual state of the switch against the commanded state. In case of
overload or wrong switch state, the block reports: FAILED SWITCH.
Short Circuit/Overcurrent Protection: diagnostics protect individual
output circuits against excess current. For Source blocks, the load
usually gets short-circuited to the DC- side of the supply. For Sink
blocks, the load usually gets short-circuited to the DC+ side.
If the output is commanded to go on and current exceeds 5 Amps for 1
ms, the circuit is automatically turned off and the FAILED SWITCH
message issued. The circuit must be reset by cycling power to the
block, or by sending a CLEAR FAULTS command from the Hand-held
Monitor or the Bus Controller.
Surge Currents: Both Source and Sink blocks handle steady-state
loads of 0.5 Amps during normal operation. Surge current protection
determines conditions for safely switching loads between 0.5 Amps First, the block must be configured with a Hand-held Monitor to:
Enter its Device Number (serial bus address).
Enter its Reference Number (required only for IC600 and IC550
series PLCs only).
In addition, unless all circuits on the block will be inputs, the Block I/O
Type must be set to either Outputs or Combination on the Program Block
ID screen.
Note: If a block is configured offline, it must be properly grounded and
have a 75 Ohm resistor installed across its Serial 1 and Serial 2
terminals.
The rest of the features can be configured either using a Hand-held
Monitor, or by sending a Write Configuration datagram to the block from
the host.and
