Use Async Reads

Starting with E3 version 3.0, operating with IOKit 1.15 or later, this Driver can operate with asynchronous readings, which makes readings faster

Monitor Program Downloads

When using asynchronous readings described on the previous option, this Driver requests readings from the physical address that variables occupy on PLC's memory. If during a communication there is a program download to the PLC, physical addresses may change, which may lead to incorrect readings of values. Select this option if there is a possibility of new downloads while this Driver is operating, which gets updated addresses immediately after this download finishes. NOTE: Using this option may turn communication approximately 2% slower

Import each property as individual Tags

When using E3's Tag Browsing, users can select whether data structures, arrays, or vectors are created as Block Tags or as individual Tags. NOTE: If users select the option to create individual Tags, it is recommended to use asynchronous readings

Start Offline

Indicates that this Driver must start without initiating the communication, so that users can change, at run time, some parameters before connection. After defining these parameters, this Driver can be freed to communicate by writing 0 (zero) to the CIP.StartOffline parameter, using IOKit's parameter-changing services. For more information, please check topic Changing Parameters At Run Time

Port ID

Specifies an output from Ethernet card and it must be equal to 1 (one, port for controller's backplane)

CPU Slot Number

Slot position where the processor is, between 0 (zero) and 255

Operation Retries

Internal retries for each reading and writing operation before informing an error

Async Read Mode

When using the asynchronous readings option, informs the type of reading optimization adopted. The Blocked mode tries to find parents, that is, items that represent the first level on the user-defined object structure on the memory map, by reading all children. This mode is recommended when most items on each structure must be read by an application.

The Non-Blocked mode, on the other hand, identifies each child item separately, requesting a reading on these items individually in a grouped request (usually each group contains approximately 30 items). This mode is recommended when only a few items on each user-defined object structure must be read by an application

CompactLogix Arrays Firmware <20 Compatibility

Select this option if using a CompactLogix controller with a firmware version less than or equal to 20.XX, which represents a shift on Array types using physical addressing (Non-Blocked)

TCP/IP Connections

Allows users to define from one to four simultaneous TCP/IP connections with a controller, aiming to improve communication performance. If communication is serial, this parameter is not used. NOTE: It is recommended to use asynchronous readings (please check the Use Async Reads option) so that connections are used more efficiently

Master Address (RS232 only)

Indicates a Driver's address (Master) for communication via serial port

Check Type (RS232 only)

Informs whether error-checking calculation when communicating through serial port is CRC or BCC
