FBM202工控模塊卡件
CMP_功能塊將模擬輸入A與外部或內部限制設置，并提供高（1）超過限制時的輸出。
動作-CMP塊可以配置為直接或反向動作。直接操作將導致輸出消失輸入A等于或大于極限時為高。
在以下情況下，反向操作將導致輸出變高：輸入A等于或小于極限。死區-當輸入a小于限值時，輸出將從高（1）輸出返回低（0）輸出-直接動作的死區設置或大于反向動作的極限+死區。外部限制-配置輸入EL時，限制設置將被忽略，輸入EL的值將用作極限值。CWE_功能塊在以下情況下可用：可選以太網通信板9是安裝在控制器中。它啟用控制器將線圈數據通過以太網。
最多可提供32個CWE_塊。積木是按順序分配，控制器范圍，每個使用最多16個開/關塊輸入，I0至IF，can
寫入a中的16個連續線圈位置目標Modbus設備。
IP地址參數用于配置目標Modbus設備的IP地址。
MB ADRES參數允許Modbus要配置的地址。當連接到其他西門子摩爾控制器，Modbus地址設置為1。在某些情況下，其他Modbus設備可能使用不同的地址，或者通過Modbus TCP/IP網關aModbus網絡可能有多個設備，每個設備具有唯一的地址。START CL參數標識位置第一線圈的。CL參數的編號標識線圈總數，最多16個，以寫UD類型參數可以配置三個寫入更新選項。1.oncE將向啟動CL（Modbus啟動線圈）寫入一次。當任何塊輸入時，控制器將寫入值更改為狀態。2.P2P將以以太網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表示寫入操作的質量，當寫入未完成時，輸出QS將變高（1）成功地這通常與由于以下原因導致目標設備無法接收數據相關：通信故障或設備配置錯誤。
CMP_ function blocks compare analog input A with an
external or internal limit setting and provide a high (1)
output when the limit is exceeded.
ACTION - the CMP block can be configured as direct or
reverse action. Direct action will cause the output to go
high when input A is equal to or greater than the limit.
Reverse action will cause the output to go high when
input A is equal to or less than the limit. DEAD BAND - the output will return from a high (1) output to a low (0) output when input A is less than the limit -
Dead BAND setting for direct action or greater than the limit + Dead BAND for reverse action.
EXTERNAL LIMIT - When input EL is configured, the LIMIT setting will be ignored and the value of input EL
will be used as the limit value.CWE_ function blocks are available when the
optional Ethernet communication board9
is
installed in the controller. It enables the controller
to write Coil data to other stations over the
Ethernet network.
Up to 32 CWE_ blocks are available. Blocks are
assigned in sequence, controller wide, with each
use. Up to 16 ON/OFF block inputs, I0 to IF, can
write to 16 consecutive coil locations in a
destination Modbus device.
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 START CL parameter identifies the location
of the first Coil. The NO OF CL parameter
identifies the total number of coils, up to 16, to
write.
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.
