最多可提供32個DWE_塊。積木是按順序分配，控制器范圍，每次使用。
數(shù)字數(shù)據(jù)是打包成16位字的開/關數(shù)據(jù)。
IP地址參數(shù)用于配置IP目標Modbus設備的地址。MBADRES參數(shù)允許Modbus地址為：配置。當連接到其他西門子時摩爾控制器Modbus地址設置為1。
在某些情況下，其他Modbus設備可能使用不同地址或通過Modbus時TCP/IP網(wǎng)關：Modbus網(wǎng)絡可能具有：多個設備，每個設備具有唯一地址。這個MB REG參數(shù)標識在Modbus設備中注冊。
可以有三個寫入更新選項：由UD類型參數(shù)配置。
1.一次將一次寫入起始CL（Modbus起動線圈。控制器將在以下情況下寫入：塊輸入值改變狀態(tài)。
2.P2P將以以太網(wǎng)塊中設置的控制器對等速率進行更新。
3.Ct將在控制器的循環(huán)時間更新。
Ct選項通常僅在寫入時間關鍵更改時使用。輸入T可用于觸發(fā)寫入。這
如果選擇了oncE選項，輸入值不變，并且可能存在擔心接收設備丟失了值。
輸出QS表示寫入操作的質(zhì)量，當寫入未完成時，輸出QS將變高（1）

DYT_功能塊執(zhí)行ON或OFF由類型配置確定的輸出延遲參數(shù)接通延遲-當輸入P為低（0）時，輸出O1為低。
如果P變高（1），則經(jīng)過計時器啟動并設置為O1達到DLY時間時為高，前提是P仍然為高的
關閉延遲-當輸入P為高（1）時，輸出為高的如果P變低（0），則已用定時器啟動并設置O1在達到DLY時間時為低，前提是P為仍然很低。
在固件1.30及更高版本中，DLY時間為在整個顯示范圍內(nèi)可調(diào)，范圍為0.00000到9999999。在早期版本中，最短時間設置為0.1。如果延遲時間設置為小于站點的掃描時間，則延遲時間將等于掃描時間。
輸出ET（經(jīng)過的時間）將從0.0變?yōu)镈LY時間值，并保持在該值，直到P重置輸出。
輸出RT（剩余時間）等于DLY時間-ET。
DWE_ function blocks are available when the
optional Ethernet communication board11 is installed
in the controller. It enables the controller to write
Digital data to other stations over the Ethernet
network.
Up to 32 DWE_ blocks are available. Blocks are
assigned in sequence, controller wide, with each use.
Digital data is On/Off data packed into a 16-bit word.
The IP ADRES parameter is used to configure the IP
address of the destination Modbus device. The MB
ADRES parameter allows a Modbus address to be
configured. When connecting to other Siemens
MOORE controllers the Modbus address is set to 1.
In some cases, other Modbus devices may use a
different address or when going through a Modbus
TCP/IP gateway a Modbus network may have
multiple devices, each having a unique address. The
MB REG parameter identifies the location of the
register in the Modbus device.
There are three write update options that can be
configured by the UD TYPE parameter.
1. oncE will write once to the START CL (Modbus
Starting Coil. The controller will write when any
block input value changes state.
2. P2P will update at the controller peer to peer rate set in the ETHERNET block.
3. Ct will update at the cycle time of the controller.
The Ct option is normally only used when writing time critical changes. Input T can be used to trigger a write. This
would be used in cases where the oncE option has been selected, input values do not change, and there may be a
concern that the receiving device has lost the values.
Output QS indicates the quality of the write operation and will go high (1) when the write is not completed
successfully. This is normally associated with failure of the destination device to receive data due to a
communication failure or a misconfiguration of the device.
DYT_ function blocks perform either an ON or OFF
output delay as determined by the TYPE configuration
parameter.
ON Delay - When input P is low (0), output O1 is low.
If P goes high (1), the elapsed timer starts and sets O1
high upon reaching the DLY TIME, provided P is still
high.
OFF Delay - When input P is high (1) the output is
high. If P goes low (0), the elapsed timer starts and sets
O1 low upon reaching the DLY TIME, provided P is
still low.
In firmware 1.30 and higher, the DLY TIME is
adjustable over the full range of the display, which is 0.00000 to 999999. In earlier versions, the minimum time
setting is 0.1. If the delay time is set to less than the scan time of the station, the delay time will equal the scan time.
Output ET (elapsed time) will ramp from 0.0 to the value of DLY TIME and remain there until P resets the output.
Output RT (remaining time) equals DLY TIME - ET.
