=
return
# Read a DINT value
=
# Write a new value

// Program-scoped tags
let value = client.read_tag.await?;
// Array elements
let array_element = client.read_tag.await?;
let multi_dim = client.read_tag.await?;
// Bit access
let bit_value = client.read_tag.await?;

let udt_val = client.read_tag.await?; // UDT
โก Batch Operations โ COMPLETED
Dramatically improve performance with batch operations that execute multiple read/write operations in a single network packet. Perfect for data acquisition, recipe management, and coordinated control scenarios.
๐ Performance Benefits
- 3-10x faster than individual operations
- Reduced network traffic (1-5 packets instead of N packets for N operations)
- Lower PLC CPU usage due to fewer connection handling overheads
- Better throughput for data collection and control applications
๐ Use Cases
- Data acquisition: Reading multiple sensor values simultaneously
- Recipe management: Writing multiple setpoints at once
- Status monitoring: Reading multiple status flags efficiently
- Coordinated control: Atomic operations across multiple tags
๐ง Basic Batch Reading
use ;
// Read multiple tags in a single operation
let tags_to_read = vec!;
let results = client.read_tags_batch.await?;
for in results
โ๏ธ Basic Batch Writing
// Write multiple tags in a single operation
let tags_to_write = vec!;
let results = client.write_tags_batch.await?;
for in results
๐ Mixed Operations (Reads + Writes)
use BatchOperation;
let operations = vec!;
let results = client.execute_batch.await?;
for result in results
โ๏ธ Advanced Configuration
use BatchConfig;
// High-performance configuration
let high_perf_config = BatchConfig ;
client.configure_batch_operations;
// Conservative/reliable configuration
let conservative_config = BatchConfig ;
client.configure_batch_operations;
๐ Performance Comparison Example
use Instant;
let tags = vec!;
// Individual operations (traditional approach)
let individual_start = now;
for tag in &tags
let individual_duration = individual_start.elapsed;
// Batch operations (optimized approach)
let batch_start = now;
let _ = client.read_tags_batch.await?;
let batch_duration = batch_start.elapsed;
let speedup = individual_duration.as_nanos as f64 / batch_duration.as_nanos as f64;
println!;
๐จ Error Handling
// Batch operations provide detailed error information per operation
match client.execute_batch.await
๐ฏ Best Practices
- Use batch operations for 3+ operations to see significant performance benefits
- Group similar operations (reads together, writes together) for optimal packet packing
- Adjust max_operations_per_packet based on your PLC's capabilities (10-50 typical)
- Use higher packet sizes (up to 4000 bytes) for modern CompactLogix/ControlLogix PLCs
- Enable continue_on_error for data collection scenarios where partial results are acceptable
- Disable optimize_packet_packing if precise operation order is critical for your application
