FBM202工控模块卡件
CMP_功能块将模拟输入A与外部或内部限制设置，并提供高（1）超过限制时的输出。
动作-CMP块可以配置为直接或反向动作。直接操作将导致输出消失输入A等于或大于极限时为高。
在以下情况下，反向操作将导致输出变高：输入A等于或小于极限。死区-当输入a小于限值时，输出将从高（1）输出返回低（0）输出-直接动作的死区设置或大于反向动作的极限+死区。外部限制-配置输入EL时，限制设置将被忽略，输入EL的值将用作极限值。CWE_功能块在以下情况下可用：可选以太网通信板9是安装在控制器中。它启用控制器将线圈数据通过以太网。
最多可提供32个CWE_块。积木是按顺序分配，控制器范围，每个使用最多16个开/关块输入，I0至IF，can
写入a中的16个连续线圈位置目标Modbus设备。
IP地址参数用于配置目标Modbus设备的IP地址。
MB ADRES参数允许Modbus要配置的地址。当连接到其他西门子摩尔控制器，Modbus地址设置为1。在某些情况下，其他Modbus设备可能使用不同的地址，或者通过Modbus TCP/IP网关aModbus网络可能有多个设备，每个设备具有唯一的地址。START CL参数标识位置第一线圈的。CL参数的编号标识线圈总数，最多16个，以写UD类型参数可以配置三个写入更新选项。1.oncE将向启动CL（Modbus启动线圈）写入一次。当任何块输入时，控制器将写入值更改为状态。2.P2P将以以太网块中设置的控制器对等速率进行更新。3.Ct将在控制器的循环时间更新。Ct选项通常仅在写入时间关键更改时使用。输入T可用于触发写入。这如果选择了oncE选项，输入值不变，并且可能存在担心接收设备丢失了值。输出QS表示写入操作的质量，当写入未完成时，输出QS将变高（1）成功地这通常与由于以下原因导致目标设备无法接收数据相关：通信故障或设备配置错误。
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.
