# Siemens S7 Input Plugin
|
|
|
|
This plugin reads metrics from Siemens PLCs via the S7 protocol.
|
|
|
|
⭐ Telegraf v1.28.0
|
|
🏷️ hardware
|
|
💻 all
|
|
|
|
## Global configuration options <!-- @/docs/includes/plugin_config.md -->
|
|
|
|
In addition to the plugin-specific configuration settings, plugins support
|
|
additional global and plugin configuration settings. These settings are used to
|
|
modify metrics, tags, and field or create aliases and configure ordering, etc.
|
|
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.

|
|
## Startup error behavior options <!-- @/docs/includes/startup_error_behavior.md -->
|
|
|
|
In addition to the plugin-specific and global configuration settings the plugin
|
|
supports options for specifying the behavior when experiencing startup errors
|
|
using the `startup_error_behavior` setting. Available values are:
|
|
|
|
- `error`: Telegraf with stop and exit in case of startup errors. This is the
|
|
default behavior.
|
|
- `ignore`: Telegraf will ignore startup errors for this plugin and disables it
|
|
but continues processing for all other plugins.
|
|
- `retry`: Telegraf will try to startup the plugin in every gather or write
|
|
cycle in case of startup errors. The plugin is disabled until
|
|
the startup succeeds.
|
|
- `probe`: Telegraf will probe the plugin's function (if possible) and disables the plugin
|
|
in case probing fails. If the plugin does not support probing, Telegraf will
|
|
behave as if `ignore` was set instead.
|
|
|
|
## Configuration
|
|
|
|
```toml @sample.conf
|
|
# Plugin for retrieving data from Siemens PLCs via the S7 protocol (RFC1006)
|
|
[[inputs.s7comm]]
|
|
## Parameters to contact the PLC (mandatory)
|
|
## The server is in the <host>[:port] format where the port defaults to 102
|
|
## if not explicitly specified.
|
|
server = "127.0.0.1:102"
|
|
rack = 0
|
|
slot = 0
|
|
|
|
## Connection or drive type of S7 protocol
|
|
## Available options are "PD" (programming device), "OP" (operator panel) or "basic" (S7 basic communication).
|
|
# connection_type = "PD"
|
|
|
|
## Max count of fields to be bundled in one batch-request. (PDU size)
|
|
# pdu_size = 20
|
|
|
|
## Timeout for requests
|
|
# timeout = "10s"
|
|
|
|
## Log detailed connection messages for tracing issues
|
|
# log_level = "trace"
|
|
|
|
## Metric definition(s)
|
|
[[inputs.s7comm.metric]]
|
|
## Name of the measurement
|
|
# name = "s7comm"
|
|
|
|
## Field definitions
|
|
## name - field name
|
|
## address - indirect address "<area>.<type><address>[.extra]"
|
|
## area - e.g. be "DB1" for data-block one
|
|
## type - supported types are (uppercase)
|
|
## X -- bit, requires the bit-number as 'extra'
|
|
## parameter
|
|
## B -- byte (8 bit)
|
|
## C -- character (8 bit)
|
|
## W -- word (16 bit)
|
|
## DW -- double word (32 bit)
|
|
## I -- integer (16 bit)
|
|
## DI -- double integer (32 bit)
|
|
## R -- IEEE 754 real floating point number (32 bit)
|
|
## DT -- date-time, always converted to unix timestamp
|
|
## with nano-second precision
|
|
## S -- string, requires the maximum length of the
|
|
## string as 'extra' parameter
|
|
## address - start address to read if not specified otherwise
|
|
## in the type field
|
|
## extra - extra parameter e.g. for the bit and string type
|
|
fields = [
|
|
{ name="rpm", address="DB1.R4" },
|
|
{ name="status_ok", address="DB1.X2.1" },
|
|
{ name="last_error", address="DB2.S1.32" },
|
|
{ name="last_error_time", address="DB2.DT2" }
|
|
]
|
|
|
|
## Tags assigned to the metric
|
|
# [inputs.s7comm.metric.tags]
|
|
# device = "compressor"
|
|
# location = "main building"
|
|
```
|
|
|
|
## Example Output
|
|
|
|
```text
|
|
s7comm,host=Hugin rpm=712i,status_ok=true,last_error="empty slot",last_error_time=1611319681000000000i 1611332164000000000
|
|
```
|
|
|
|
## Metrics
|
|
|
|
The format of metrics produced by this plugin depends on the metric
|
|
configuration(s).
