FBM202工控模塊卡件
CMP_功能塊將模擬輸入A與外部或內(nèi)部限制設(shè)置,并提供高(1)超過(guò)限制時(shí)的輸出。
動(dòng)作-CMP塊可以配置為直接或反向動(dòng)作。直接操作將導(dǎo)致輸出消失輸入A等于或大于極限時(shí)為高。
在以下情況下,反向操作將導(dǎo)致輸出變高:輸入A等于或小于極限。死區(qū)-當(dāng)輸入a小于限值時(shí),輸出將從高(1)輸出返回低(0)輸出-直接動(dòng)作的死區(qū)設(shè)置或大于反向動(dòng)作的極限+死區(qū)。外部限制-配置輸入EL時(shí),限制設(shè)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(wǎng)通信板9是安裝在控制器中。它啟用控制器將線圈數(shù)據(jù)通過(guò)以太網(wǎng)。

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.
