Surge immunity

Wiring systems subject to surges from lightning strike coupling must be equipped with

external protection. One specification for evaluation of protection from lightning type surges

is found in EN 61000-4-5, with operational limits established by EN 61000-6-2. S7-1200 DC

CPUs and signal modules require external protection to maintain safe operation when

subject to surge voltages defined by this standard.

Listed below are some devices that support the needed surge immunity protection. These

devices only provide the protection if they are properly installed according to the

manufacturer's recommendations. Devices manufactured by other vendors with the same or

better specifications can also be used:

Technical specifications

A.1 General technical specifications

Reverse voltage protection

Reverse voltage protection circuitry is provided on each terminal pair of +24 VDC power or

user input power for CPUs, signal modules (SMs), and signal boards (SBs). It is still possible

to damage the system by wiring different terminal pairs in opposite polarities.

Some of the 24 VDC power input ports in the S7-1200 system are interconnected, with a

common logic circuit connecting multiple M terminals. For example, the following circuits are

interconnected when designated as "not isolated" in the data sheets: the 24 VDC power

supply of the CPU, the sensor power of the CPU, the power input for the relay coil of an SM,

and the power supply for a non-isolated analog input. All non-isolated M terminals must

connect to the same external reference potential.

WARNING

Connecting non-isolated M terminals to different reference potentials will cause unintended

current flows that may cause damage or unpredictable operation in the PLC and any

connected equipment.

Failure to comply with these guidelines could cause damage or unpredictable operation

which could result in death or severe personal injury and/or property damage.

Always ensure that all non-isolated M terminals in an S7-1200 system are connected to the

same reference potential.

DC Outputs

Short -circuit protection circuitry is not provided for DC outputs on CPUs, signal modules

(SMs) and signal boards (SBs).

Technical specifications

A.1 General technical specifications

Relay electrical service life

The typical performance data estimated from sample tests is shown below. Actual

performance may vary depending upon your specific application. An external protection

circuit that is adapted to the load will enhance the service life of the contacts. N.C. contacts

have a typical service life of about one-third that of the N.O. contact under inductive and

lamp load conditions.

An external protective circuit will increase the service life of the contacts.

Internal CPU memory retention

● Lifetime of retentive data and data log data: 10 years

● Power down retentive data, Write cycle endurance: 2 million cycles

● Data log data, up to 2 KB per data log entry, Write cycle endurance: 500 million data log

entries

Note

Effect of data logs on internal CPU memory

Each data log write consumes at a minimum 2 KB of memory. If your program writes small

amounts of data frequently, it is consuming at least 2 KB of memory on each write. A better

implementation would be to accumulate the small data items in a data block (DB), and to

write the data block to the data log at less frequent intervals.

If your program writes many data log entries at a high frequency, consider using a

replaceable SD memory card.

A.3 Digital I/O modules

Note

The high-speed (200 kHz) SBs utilize "sourcing" inputs. The standard SB (20 kHz) utilizes

"sinking" inputs. Refer to the specifications for the digital inputs and outputs (Page 384).

The high-speed (200 kHz) outputs (SB 1222 and SB 1223) can be either sourcing or sinking.

For sourcing outputs, connect "Load" to "-" (shown). For sinking outputs, connect "Load" to

"+". Because both sinking and sourcing configurations are supported by the same circuitry,

the active state of a sourcing load is opposite that of a sinking load. A source output exhibits

positive logic (Q bit and LED are ON when the load has current flow), while a sink output

exhibits negative logic (Q bit and LED are OFF when the load has current flow). If the

module is plugged in with no user program, the default for this module is 0V, which means

that a sinking load will be turned ON.

• Change to a higher quality cable

• Reduce the circuit/components from 24 V to 5 V (if the product is rated for low voltage

operation. Refer to complete specifications in the S7-1200 Programmable Controller

Application / system can evaluate battery status

Refer to the S7-1200 Programmable Controller System Manual, Chapter 2, Installation for information about installing

the BB 1297 or replacing a battery in the BB.

The BB 1297 Battery board is used for applications where the real time clock retention time

is beyond one month. Features of the BB 1297 Battery board are shown below:

● Supports time of day clock during PLC power off. The S7-1200 CPU, in combination with

the BB 1297 Battery board, supports the Time of Day clock retention during a power off

period of the application for up to one year.

● Only one BB 1297 Battery board or other SB can be used at a time.

● Hot plugging / hot swapping is not allowed. The BB 1297 Battery board is only

exchangeable or pluggable while the CPU is powered off. While the CPU is powered off,

and the BB 1297 is removed to exchange the actual battery, the internal super cap will

hold the time of day while the user replaces the battery.

● The CPU "Maint" LED indicates when a replacement battery is needed.

● The user program allows you to monitor or check on the status of the battery, and battery

board and allows a user message to be displayed on an HMI or web server.

A.8 RTD and Thermocouple modules

A.8

RTD and Thermocouple modules

The thermocouple (TC) modules (SB 1231 TC and SM 1231 TC) measure the value of

voltage connected to the analog inputs. This value can be either temperature from a TC or

volts.

● If voltage, the nominal range full scale value will be decimal 27648.

● If temperature, the value will be reported in degrees multiplied by ten (for example, 25.3

degrees will be reported as decimal 253).

The RTD modules (SB 1231 RTD and SM 1231 RTD) measure the value of resistance

connected to the analog inputs. This value can be either temperature or resistance.

● If resistance, the nominal range full scale value will be decimal 27648.

● If temperature, the value will be reported in degrees multiplied by ten (for example, 25.3

degrees will be reported as decimal 253).

The RTD modules support measurements with 2-wire, 3-wire and 4-wire connections to the

sensor resistor.

Note

The RTD and TC modules report 32767 on any activated channel with no sensor connected.

If open wire detection is also enabled, the module flashes the appropriate red LEDs.

Best accuracy will be achieved for the 10 Ω RTD ranges if 4 wire connections are used.

The resistance of the connection wires in 2 wire mode will cause an error in the sensor

reading, and therefore accuracy is not guaranteed.

Note

After power is applied, the module performs internal calibration for the analog-to-digital

converter. During this time the module reports a value of 32767 on each channel until valid

data is available on that channel. Your user program may need to allow for this initialization

time. Because the configuration of the module can vary the length of the initialization time,

you should verify the behavior of the module in your configuration. If required, you can

include logic in your user program to accommodate the initialization time of the module.

Thermocouple values below the under-range minimum value are reported as -32768.

Thermocouple values above the over-range minimum value are reported as 32767.

Internal cold junction error is ±1.5 °C for all ranges. This adds to the error in this table. The module requires at least 30

minutes of warm-up time to meet this specification.

For the 4-channel SM TC only: In the presence of radiated radio frequency of 970 MHz to 990 MHz, the accuracy may

be degraded.

Note

Thermocouple channel

Each channel on the Thermocouple signal module can be configured with a different

thermocouple type (selectable in the software during configuration of the module).

Thermocouple filter selection and update times

For measuring thermocouples, it is recommended that a 100 ms integration time be used.

The use of smaller integration times will increase the repeatability error of the temperature

readings.

To maintain module resolution and accuracy when the 400 Hz filter is selected, the integration time is 10 ms. This selec-

tion also rejects 100 Hz and 200 Hz noise.

Note

The module reports 32767 on any activated channel with no sensor connected. If open wire

detection is also enabled, the module flashes the appropriate red LEDs.

Best accuracy will be achieved for the 10 Ω RTD ranges if 4 wire connections are used.

The resistance of the connection wires in 2 wire mode will cause an error in the sensor

reading and therefore accuracy is not guaranteed.
